Have to agree with @Gibson99- the idiots got what they deserved, but in some of these clips, the car in the rear could have avoided the crash had they slowed down, and in a lot of places that would be enough for them to be declared at fault Especially liking the 'bus' clip, for that is what should be allowed and done with brake-checkers, with them paying all damages while receiving a lifetime driving ban.
As a ex bus driver I agree with SawMaster, most bus companies will tell you your passengers are your first priority, the idiot driver in the car is not. Still...giving them the extra shove is a good feeling
