If they could have gotten the rig tire to explode it would have been deadly. I know a man that died in a truck tire shop. I had 4 car tires blow in my face and that too the visor of a baseball cap clean off. The way they blew for me was the tire failed right around the rim. In truck shops what you see is pieces of the roof patched up from a split ring failure.

I had two Terror Tire stories. The first was a blowout next the passenger side of a 64 Corvair, that side of the wind shield cracked and the little tiny vent window on the side gone forever and no idea where. What was far more dangerous combines the two dangers. About 100' behind a semi, the entire recap, retread tire peeled off at 80 in my car or about 69 or 70mph. I watched in awe and braking as more than a yard of rubber did a flip and with a twist. My change in speed made the hit broadside and the entire windshield shattered and me in the middle lane of the Washington Beltway. If the tire hit straight on with the mass directed along the length, it could take a head off.

I had once a truck tire exploding just behind me while I was passing by it on my bicycle, it was going the other way, it was so close that I felt the wind on my back and had my right hear whistling for over an hour I can assure you if I was two meters behind I would be in the hospital with several broken bones and probably internal damage too. It's no joke. My father in a trip to France by car in the 80s, while passing a truck a tyre exploded hit the car on the side, smashed both doors and send the car off road.

Loving the nostalgia of these shows. Long before this episode (back in the 80s to 90s), I used to get into the slipstreams of semi-trailers at night on the highways over here in Australia. Back then, I knew that it reduced drag because you can feel when you're getting into the 20-40% zone. I mean, I'm using percentages based on the Mythbusters video, but yes, you can feel when you're getting into the slipstream. I also used the effect when I was driving a 6-tonne Pantech body truck. I could get right up into the slipstream and have a chat on the CB to the trailer driver. He'd let me know when it was clear to pass and I'd get that little boost...almost like NASCAR, but on the outback highways in Australia. In trucks.

Yeah honestly it's wild that my dad taught me to drive in Australia including by deliberately tailgating big trucks to get in the slipstream.

@RICHARD-mn3nd 20 күн бұрын

Two points. First. I slip streamed behind a semi to see if there was any effect. There was, but I might have two metres from the truck (at 100Km/h), and it was very effective. Determined by assessing the amount of "prod" on the pedal. It was so terrifying that I drove there for about 15-30secs only, before dropping back. Second. A true story of trucking terror. This happened north of Coomanduke in Sth Australia in the 60's. Three truckies were driving at night and the last two were using terror to stay awake by tailgating the first truck. The first driver fell asleep and ran off the road, fortunately it was flat farmland, and of course the last two followed him. Nobody got hurt and the vast majority of people thought it was funny!!

In Iceland from 15 you could get a licence for a scooter that could go 45 kph, but the max kph is 90. What guy's did to get to 90 was to drive behind a truck dangerously close to get the bike up to 90 kph.

A bit of pedantic physics here... the pieces of tire going backwards from the truck were going about 40 mph WITH RESPECT TO THE TRUCK. In the test, the truck was going 0 mph, but on the highway it would be going 55, so the piece of tire would only be going 15 mph. However, a car also going 55 mph behind the truck would see the piece coming at him at 40 mph. A MUCH more scary scenario is if the tire piece came off the TOP of the tire, which would be going about twice the speed of the truck, or 110 mph. Into oncoming traffic that would be going 55 mph in the other direction, so closing speed of the chunk of tire would be 165 mph. Ouch.

@rogerstalder7184 10 ай бұрын

Big Trailer does have an INSANE low pressure zone behind them. you can test this even better with a vehicle with 2 wheels, bike, scooter someting like this. I did this with my scooter who did drive 50 mph. thats just what our speed limit is on Landroads. i drove up to them and like 2 meters behind them i had to slow down, or my scooter did speed up to almost 90 just because i had no wind pressure anymore. and then i barely did need to hit the gas, and could drive 80 miles with like 10% fuel usage.

@BananaMana69 10 ай бұрын

Yeah a bicycle can actually achieve highway speeds while in that zone, the trucks low pressure actually pulls it along. You can draft pretty well behind any vehilce on a scooter though. Me and a friend used to take long rides on our scoots and wed take turns drafting behind each other.

@mittelwelle_531_khz 8 ай бұрын

@@BananaMana69well, speaking "physics", just to be precise: the low pressure zone behind the truck doesn't "pull", same as vacuum doesn't "suck". It's rather that the high(er) pressure behind the low(er) pressure does PUSH. Granted, at the "macro level" - ie. when you consider the effect of lots and lots of little "massive" particles (like the molecules/atoms of a gas) - it's hard to tell the difference, so, yes, "colloquially" speaking you're right.

With the car into the trailer,would it make a difference if the car was front,rear or 4 wheel drive?

@answeris4217 10 ай бұрын

4 wheel drive they would have broke something. That's my thoughts. The transmission or the transfer case or a driveshaft. Your going from 55 to zero.

@Billy.Nomates 10 ай бұрын

@answeris4217 that's what I thought,as the back wheel would be going at a different speed to the front on the trailer

@leoarc1061 10 ай бұрын

In a 4 wheels drive it would depend on the central diff. Some are designed to expect sudden handbrake turns which, in a sense, are not too dissimilar to this case. A FWD car would either bog down the engine, potentially burning the clutch, and/or break a couple of gears.

....and then the air pressure between the truck and the trailer fails and the trailer does an automatic emergency brake (wheels just locking completely) with zero warning... Seriously, the driver can be driving as safely and consistently as humansly possible, but when the wrong thing breaks, you're a goner if you're driving too closely behind it.

@no-damn-alias 8 ай бұрын

I wonder why there's no such thing like being flat towed behind a truck. You pay the trucker a small amount of money that is lower than what you'd have spent in fuel but higher than the truckers extra fuel consumption. You stay in your vehicle and can relax during the trip.

@johntaphouse5235 10 ай бұрын

the thing is driving that close behind a truck causes the truck to experience more drag as your car is interfering with the air pocket.. as a truck driver i know without seeing when a car or other truck is right behind me, it screws up the vehicles handling a bit.. and i have to assume adds to my fuel bill... so dont be surprised if im not too happy to have you gating me for too long

@Wolf-ln1ml 23 күн бұрын

Plus of course if the air pressure fails between the truck and the trailer (don't know the English terms, but I'd be happy to learn them 🙃), the trailer will simply go into "emergency brake mode" without a shred of warning... There are so many skid marks of exactly that here on the Autobahn, I just hope that it never happens to me when I've got a heavy load... (with a light load, you can at least drag the trailer with it's locked wheels off onto the emergency lane...)

I once had my front license plate actually go under the rear bumper of a Lincoln, and about an inch from the Lincolns license plate inside the bumper recess to draft it. It worked amazingly well for my cars fuel efficiency, but the lincoln got worse mileage due to it actually pulling my car due to the way the drafting works.... (a friend was driving the lincoln, not a random car on the hiway).... ..if you try this, keep an eye on the heat gage, it will climb quickly with no wind cooling the radiator...

If both brake at the same time, perhaps yes, but since the car can’t see shit there’s no hope of braking at the same time. You only need to look at the number of (deadly) accidents of cars running into (or more under) the back of a truck to know drafting is an idea only numb skulls consider.

You always have to calculate with about a 1 second reaction time for a normal driver _(much_ more if you're tired due to getting up early or a long work day or a long drive or...). At 50mph (80kph), you drive about 22m in one second. At least here in Germany, the technical requirement for a truck (checked every six months) is to be able to brake _at least_ at 0.5g (0.5*9.81m/s²=~5m/s²). So during that one second, the truck will have slowed down by at least 5m/s=18kph=11mph, _and_ you'll be about 2.5m closer to it already before your brain even registers that you need to brake. And cars don't brake all that much faster...
