[Traster]

Running into traffic to pick a fight with them? Throwing your bike in front of their car to cause a collision? Jumping onto their bonnet to try and pretend you're being run over?

The guy is quite literally taking the law into his own hands and it's very clear that running around trying to cause car accidents is making people less safe, not more. In many cases the "accident" he claims to want to prevent is caused by his actions.
