Chuck Marohn also makes the point that converting nominal highways to actual highways by eliminating all the driveways and greatly reducing intersections, can more than make up for a very low speed limit inside the city, making overall trips actually faster. It's the stroad-everywhere thing, in which a roadway is multilane but with lots of driveways and intersections both inside and outside cities, that wastes so much time and space, and facilitates crashes. Slow streets in the city, paired with limited intersection highways outside, could yield safety as well as greater driver satisfaction.

yes and drivers (at least men, maybe women too) do not attenuate this overconfidence until they actually get into accidents (according to Matthews & Moran 1986). Meaning that drivers rely on historical data to inform their confidence in driving ability. This is a great reason to raise the driving age to 25. If drivers do not attenuate their overconfidence until after they cause crashes, then everyone else is essentially acting as their guinea pigs. Matthews, M. L., & Moran, A. R. (1986).

Watch them ALL speed and then listen to those idiots argue that it's safer when everyone speeds. Most people shouldn't be allowed to operate dangerous machinery in public, just watching them for five minutes proves that and yet we do nothing about it.

In The Netherlands we dropped the speedlimit on motorways to 100 (down from 130) km/h in order to reduce emissions. The drop in accidents and fatalaties was very noticeable.

The part where you say "lets not permanently disable people to save a few minutes on your commute" hit me hard. My aunt was run over in LA while riding a bike about a decade ago and is still in a vegetative state. Then a few years ago I was in a crash myself. I got rear-ended at a light by someone who didn't stop. I lost my sense of balance from it and walk with a cane. Both times, they ran off and were never held accountable. In both cases, a reduction of speed might have saved us from life-long disabilities. My aunt wouldn't be permanently brain damaged, and I wouldn't be stuck walking with a cane so I don't fall over. Things need to change, obviously a lot more than just raw speed. Your videos give me hope that people will listen soon, and start aiming for those changes.

I work at a childcare center and we have to cross the parking lot twice to get to our playground. The first crossing is very short and very few cars go through it so it's pretty safe. The other one is just past the entrance and therefore every single car that enters has to go through it. There's a stop sign on either side of the crosswalk yet we constantly deal with people rolling right through it. Even when we have a group of 15 children and 4 adults taking up literally the entire space they'll still try to roll it and squeeze around us. Like dude, you can wait an additional 15 seconds for literal toddlers to finish crossing. Some of the older kids have taken to making their own stop signs and they spend part of their time in the playground standing by the fence that's right by the one sign waving them and shouting at drivers to stop. When a 5 year old knows how to obey traffic laws better than an actual licensed driver then you know it's bad.

That's why unfortunately changing speed limits isn't enough. Drivers drive as fast as they feel like they can without getting in trouble. So over time, cities need to make roadway improvements that actually encourage slower speeds, and traffic laws need to be paired with enforcement. The more regular use of speed cameras in Europe is part of why something like this is more effective than in the US.

My first job after getting driver license was pizza delivery, In a small town in Poland. In Poland cities are mostly limited to 50 km/h, and residential areas are limited to 30 km/h, with some exceptions in bigger cities on major roads, where the limit is 70 km/h. At first, as a new driver I was speeding all the time to get the food on time, I was young and dumb. I had one client that ordered everyday and was on the other side of town (around 5-7km from the pizza spot), and one day I decided to test how much time i gain by speeding. So i took the timer, measured the time one day while speeding, and the next day I measured time without speeding. The difference was 10 seconds. I stopped speeding after that. No matter what, something is going to stop you in the town sooner or later, it can be red lights, stop sign or give way sign, turning left, roundabout, or just pedestrian walking on the crossing(you have to give way for pedestrians on crosswalks in Poland). Speeding just don't make any sense in cities, best way to save time driving in cities is to drive dynamically by paying attention to the road and going as soon as you can go, BUT NOT FAST.
@corcorsma Ай бұрын
Agreed, I had t he same but on the highways. I didn't measure it as precisely as you did, but after I got one really hefty fine for 40km/u speeding (the road was empty though) I calculated what the difference was, if I could drive on average 25 km/h faster on the parts of the highway where it would be 'safe' in my experience to do so. The difference was 4 minutes on the entire trip... It's never more than a few minutes. Unless you have a trip that's 1 hour, 1,5 hour, or longer, almost exclusively on the highway, and you are able to drive faster without interruptions from other traffic. In that case... the difference might be 10 minutes or a bit more... Still, the downsides: safety, fuel consumption, danger of fines or worse. (Another thing: fuel consumption at 120 km/u is a lot more than 100 km/u - not +20%, but more like +40%!)

People think in that immediate moment with little awareness of the bigger picture. Basically, most people are crap drivers.

As a truck driver who drives through multiple cities on a daily basis, I've learned that the speed limit on the interstate within the city limits is irrelevant because overall, traffic never really achieves anything remotely close to the posted speed limit. Even if they do, it's only for a short while before everyone comes to a stop again. So when I'm on an interstate, driving through a city i automatically know to expect a much lower speed limit than what's posted on the signs. Therefore i put about 40-50 yards of space between me and the vehicle in front of me so as to allow traffic to freely change lanes and merge into and off of exit ramps while going along with the flow of traffic. By doing this I'm saving fuel because my speed isn't fluctuating so abruptly up down.

It's good for business. Faster cars means higher risks so higher insurances and thus more money. The opposite is also true though, if everybody drives slow, and nobody ever gets hurt, the prices go down, and people pay for something that never happens. However, most of the time, that is not the situation that we are in right now. Best part though is not having to pay for insurance at all. If you don't own a car, you don't need insurance for it, and it costs you nothing.

So after I almost got hit the same spot 3 times in one week, I chose to take a longer route that would reduce conflict points between me and the cars..... So I had to lose time, or risk my life. While that driver thought it was fine for him to demand that he should be allowed to noy yield for me while crossing my road, so he could save 10 seconds.

Ever since I've learned (from you) about the whole "designed for speed" thing I've started noticing how speed limits mostly don't fit the roads/environments. For example, the road between my nearest town and my village is 70 km/h for the most parts but 90% of people will do 90+ because that just feels about right and safe. On the other hand, the road through my village is 50 km/h but I find myself usually going less, about 40, because it feels appropriate for it's design and the occasional cyclist or a pedestrian (small village, no pavements). It really changed how I look at different roads I drive on, especially when I see someone speeding or going very slow.

I think this was an argument for how you could just set no speed limit on a road, measure the average speed that cars travel at, then multiply by some factor, to get a sensible speed limit for that road - because drivers, on average, tend to pick close to a sensible speed on their own. I've also seen cones and temporary speed signs set up for roadworks, with no workers to be seen anywhere. The speed limit was reduced to 30k or 50k from the normal 100k, but no-one was actually complying with the reduced speed limit because there was no rationale for it to be that low.

But at that point in the video I still wasn't entirely sold lower speeds are good. By the time you got to the point where you discuss not needing lights and stop signs, that was when I was sold. All the slowdowns made sense. I know I don't go as fast as the speed limit in most cases in city driving. It's just the infrastructure that hasn't adapted with both safe driving speed as well as reducing congestion. I'm all on board now. Reduce the speeds but there has to be major infrastructure redesign along with it to reduce stop signs and lights. Safer and better driving practices.

Yes, exactly - the benefits of the higher speed efficiency is only truly felt in places like a freeway. I live off a highway and the speed limit is 55mph, which should mean I am pretty efficient, but due to frequent stopping at stoplights, the difference is quite minimal compared to city driving. Maybe +1-2mpg, the kinds of gains you can see just by having more favorable driving conditions in general (e.g., warm weather versus cold). By contrast, freeway driving routinely nets me +10mpg. Anywhere that has frequent stopping is not really going to become that much more inefficient due to lowering the speed limit (but, lowering the speed limit can lend itself to road design that reduces the need to stop overall, raising efficiency!) Aside from that, electric motors are very efficient at lower speeds unlike ICEs - hence why many hybrids get fantastic mpg both in and out of city (but typically, even better in city than on freeway)! Assuming we will continue on the track of developing hybrids/EVs and slowly replace pure ICEs, the whole "more efficient at higher speed" becomes a moot point anyway.
@HappyBeezerStudios Ай бұрын
The efficiency thing is probably the result of engine rpm. They tend to have maximum torque and hp at a certain range, usually in the upper end. And to get your small car with a small engine to 5000-6000 rpm means driving 50+ But a different gearbox would probably change that. If there were a "zeroth gear" and a "1.5th gear", optimised for maybe 15 and 30 km/h range, efficiency in slow city traffic would be no worse than the usual 50-70-100 km/h range. Plus it would give the high efficiency rpm at a speed with even less wind resistance. I even noticed that when biking, high pedal rpm is less strenuous, more flexible for speedup and -down and leaves higher gears for going fast.
@or2kr Ай бұрын
@@HappyBeezerStudios usually higher load, like about 80% equates to the highest efficiency, especially at around 2500 rpm, so lower or higher rpm or lower load will all decrease efficiency. With the highest gear you get higher load at a given speed, but that gear isn't usable at 30kph, so you have to drive at an even lower load. Now this only means that you convert fuel into a given amount of energy less efficiently, it doesn't automatically mean that you'll actually use more fuel for a given distance
@Robbedem Ай бұрын
@@HappyBeezerStudios no, that's not how it works. Engines use fuel per rotation. So to use the least amount of fuel possible, you want to have the least amount of rotations that still allow you to provide enough energy to move. The higher the gear setting, the less rotations per distance traveled. And to go slower, you need to use a lower gear setting to prevent stalling the engine (going below the minimum rpm). So if going slower requires you to reduce the gear, you will lose efficiency.

Perhaps between one cereal item and another, 10 yards away, with no interruptions. However, in reality, complex routes between aisles and products, and moving around other customers running would mean abrupt stops all the time, trips and falls. If everyone just moves along at a regular orderly pace, your overall grocery shopping time would likely be reduced, with WAY fewer injuries. Similar to evacuating an aircraft during an emergency, it's actually fastest if everyone moves along at a calm, measured and consistent pace.

Something nice that I started to see in Germany last year are bicycle streets. Mainly smaller, residential streets where bikes have priority over cars and cars are only allowed to drive up to 30km/h. And since the signs are the bicycle lane sign on a white rectangle with Fahrradstraße written under it, people also easily understand that cars aren't the big player there. I feel like adding more of those in cities would be nice in multiple ways. 1. There is no discussion about the city lowering the speed limit since it only involves a handful of minor streets at one time, greatly reducing the amount of people complaining. You are just making sure bikes get the place in traffic they deserve. And by the time the typical complains start, the city can just point towards the already existing streets and show how they aren't a problem. 2. It makes the roads safer for anyone. I recently started biking to work when the weather is nice (otherwise it's the bus for me) and I prefer smaller side streets and bike paths next to larger streets compared to driving on larger streets. Luckily my route allows me to avoid them apart from traffic lights and other street crossings. 3. Reduced noise levels will make more people living in those streets push for the change since it makes their homes quieter and more desirable

Part of being an above-average driver is choosing the correct speed for the conditions/scenario at hand. I live in a rural area, and there is a blanket speed limit of 80km/h on nearly all roads in the countryside (Ireland). However, on some parts of the road network, my chosen speed goes well below 20km/h - blind bends on single-track roads where I might (and have often) met pedestrians, cyclists, horses, and tractors. What might make me an above average driver is that I've tried to train myself to choose a good, often way lower (but also occasionally higher) than the limit, speed for the scenario. PS: I recommend an EV for rural driving on winding, narrow roads - with single-pedal driving (press to drive, lift off to regeneratively brake), you can make good, safe progress, while constantly varying your speed to keep to the "I can stop within the distance I can see to be clear" rule. I find that drivers of manual, petrol/diesel vehicles tend to get sick of constantly pedal-swapping to brake/accelerate and change gear, so start to carry too much speed into corners, because it's easier, and confirmation bias means that they get used to doing it, because it always seems to work out (until suddenly, it doesn't).

17:35 - FYI from a car nut: this is not an issue on 90% of vehicles made within the last 5 years. Newer combustion-only cars almost all make use of 8+ speeds in their transmissions or use a CVT, allowing them to hold the engine at the most efficient RPM and load percentage even at very low speeds. Back in the 90s when most automatic transmissions had only 3 or 4 fixed ratios to work with, this was an issue and you'd have your engine sustaining an unnecessarily high RPM at 30kph. Hybrids are also growing in popularity and will basically never run the engine at low cruise speeds like 30kph unless they're charging the battery. This is basically an outdated argument, and will only become more outdated as EVs and hybrids continue to replace combustion-only vehicles.

I'm so glad you touched on the factor of actual average speed due to stoplights. For the places I regularly commute to, I've noticed that the average speed comes out to to around 35kph, and that's especially true for the routes with 50kph+ speed limits.
@Knackebrot Ай бұрын
People also argue that the road has less capacity because 50kph is faster. But they forgot that a driver holds a bigger distance to the car in front at higher speeds. -> Same throughput (maybe less). It also makes driving less attractive in terms of time, making more people not drive.
@jamesphillips2285 Ай бұрын
This is made explicit with the "2 or 4 second rule": you are supposed to increase the distance at higher speeds because our reaction time does not really change at higher speeds. Also if I see vehicles ahead or behind bunched up: I will increase my follow distance because I am now driving for 2.
@Robbedem Ай бұрын
I did this calculation once. Do you know what the most efficient speed is to get as many people from point A to point B ? It's 4 km/h. So not 50, 40 or even 30. But 4. Strangely this is the speed we use for walking. Coincidence?

Oddly enough slower speeds means traffic can keep moving which generally means moving faster. another reason why stop signs suck is that your required to completely stop compared to yield signs which you don't need to stop and can just slow down keep rolling and pick up speed again which is alot easier moreso with manual cars.

Serious Injury really is not talked about enough. My Dad had a serious car crash 2 years ago and is still heavily depressed. The financial impact is also often not mentioned. Even when you do survive and your injuries heal, treatment costs or loosing your job will affect you for years to come. He has racked up medical bills to a combined 2,3 million euros so far, and they want their money back from someone, so even when your not hurt, being involved or even having caused an accident all by yourself may cost you 2,3 million euros plus any compensation for the victim, who'll have to live with your mistakes for the rest of his life (which are costs that can go into the seven digits, and are not guaranteed to be covered by your insurance). So even car drivers should strive for lower speed limits, you can ruin your own life financially in a timespan that's too short for you to conceive.

After only a short time of driving, I've come to realise that instead of simply putting up signs that can be ignored, it makes far more sense to tailor the road width to the desired speed. On narrow roads, the max comfortable speed for the driver is much lower than a wide street with a 30kmh speed limit

ie, "Traffic calming". Change the road so that it appears (and is) more hazardous for drivers to drive at higher speeds on. Of course you can't make it too obvious overwise drivers will recognize that you're introducing artificial obstructions to their passage.

It’s a little bit of both. Just putting up seemingly random signs doesn’t do much on its own, but depending on how the street already looks it can be all that is needed. The problem with 50km/h streets is, other drivers expect you to go that speed, even if the street isn’t designed for it. Germany is currently still stuck on an old law stating the basic city speed is 50 and any exceptions need to have a reason. My German home state (Baden-Württemberg) introduced a measure a couple of years ago which allows 30km/h even on throughfare streets, if the street is too loud (which applies to basically all of them). Through that many towns and cities have lowered speed limits on roads, which used to be 50 without any changes to the street itself. And while these measures were initially often unpopular when introduced, after a few years everybody just got used to it and traffic slowed down. I moved to a neighbor state a couple years ago and I keep driving through towns and villages thinking to myself, why is there no 30 sign here, this street obviously is too narrow and windy too be safe at 50.
@svr5423 Ай бұрын
and more accidents occur on narrower roads. Since some people driver slowe than the speed limit, there is much more overtaking. Cyclists are also more endangered as the cars simply don't have that much space to maneouver around them. Bad idea. Wide roads means safety.

at 6:40 you got YOUR high school physics teacher mad! bigger brakes almost never help with stopping distance since almost any disc brake can lock up the wheel, what helps is bigger tires or better weight distribution, since the braking force is limited almost exclusively by traction. bigger, better brakes are useful on the track, or on extremely heavy vehicles, where the limit becomes how much heat the brakes can absorb and dissipate and not how much traction the tires have.
@iskierka8399 Ай бұрын
Bigger tyres also don't help, friction is dependent on the weight through the surface, not the size of it. The reason performance vehicles have large tyres is to use softer, fast-wearing compounds that *do* have more friction, while making them last long enough to use for a whole race under race forces.
@cagasbura420 Ай бұрын
@@iskierka8399 that's not entirely true. while normally friction is just a product of normal force and friction coefficient, tires behave in a peculiar way, as their deformation per weight diminishes as weight increases. kzfaq.info/get/bejne/ed94aNuAyNm8qKc.htmlsi=EFSsOk9OGU2TaTtc this video goes more in depth on it and explains it better than i can. that's also why heavier vehicles do brake worse, if not, adding mass would proportionally add normal force and a vehicles ability to slow down would be entirely dependant on the friction coefficient between the tires and the ground.

@@cagasbura420 Larger vehicles don't brake worse, though, at least not significantly; see Volvo (and now all other euro manufacturers) safety systems, stopping fully loaded trucks in the same distance as a car. They took more distance in the past due to the difficulty of ABS on trailers, so to avoid jacknifing the trailer brakes would be intentionally undersized, but on a modern truck the stopping distance is virtually the same; any small distance difference that *can* be observed is explained by trucks using harder tyre compounds, because they put so much weight through each tyre that they can't use a soft, high-grip rubber due to how often it'll need replacing.
@madattaktube Ай бұрын
Also bit of a nitpick, but for all the many problems with the proliferation of large trucks, the increased *mass* lowering pedestrian safety isn't one. The mass of a pedestrian is already at least a magnitude lower than even a small car, so the weight of the trucks increasing has a pretty much neglible impact on predestrian safety. It only really matters in vehicle-vehcle collisions where the vehicles would have otherwise been a similar mass.
@iskierka8399 Ай бұрын
@@madattaktube True, but the *size* and especially *height* of the trucks, both of which strongly correlate with the weight, do negatively correlate with pedestrian survivability, since a vehicle that an adult would roll onto instead flattens them, and a child isn't seen at all.

It is likely that the road was there before, then a petrol station, than a cafe and a motel, and slowly a town grew around the road. The question is that this road should now either be routed around the town (which might impact local roadside businesses that define the town and provide most of the employment - although that can be mitigated), Or make crossing the road safe for everyone with pedestrian underpasses, balanced traffic lights, and such. Of course this being the land of Freedom (mostly from common sense and responsibility it seems), they have taken the third option - do nothing and just factor in the dangers of cars into their everyday life.

A month ago I was riding my bicycle in a mixed zoning street (with cars, bikes and pedestrian on the street). Suddenly a car drove past me and pushed me to the side, I tried circumventing him but he speeded up again and pushed me to the side. Then he lowered his window and started screaming at me that I had cut him off which I hadn’t, I merely happened to overtake him because there were obstacles meant to slow down drivers. When he was finished, he drove off with at least 50 kph in what is mostly a pedestrian and biking street (and one of if not the busiest street in the city.) I was so shocked, I thought he was going to run me over, I mean, he almost did.
