Did you just film yourself cycling through a red light.

cycling on the pavement (looked but didnt see any shared space signs for cyclists and pedestrians), failing to stop for red lights (red lights still apply to cyclists), then rides into on coming traffic by not going round the roundabout the correct way. complain all you want about the road works but you are giving cyclists a bad name which most likely more people will focus on. the road works are close enough to the roundabout that traffic would block the roundabout or traffic would not be able to clear when entering the roundabout, so they have to put a traffic light system to control the roundabout. they should probably put extra teams to progress the work quicker to clear the road works but it is what it is, once people know about it, many will find different routes.
