Biker is the he moron. He kicked the door. He started the whole chain of accident events.
That was intentional hence he is a moron. We don't know why the driver reacted the way he / she did so untill we know it's hard to pass judgement.
The initial reaction of the driver of the car is to swerve INTO to bike. Aggressive move, the kick from the biker was dumb, the move by the driver could have killed the biker and may give a hint of what had happened before the kick. Still no idea why the biker kicked the door, not shown here. There was a reason for that kick. We disagree, fine by me. Driver is the moron.
Have had cage drivers - for no reason at all - take an aggressive move to try to run me off the road. Not lately, and thankfully, not that frequent. But it has happened and all I was doing was staying in my lane while they intentionally tried to swerve into me, running me onto the should or actually off the road. Not funny, but from the big grin on one of the $%#&* faces, you would have figured he found it funny. So I have a prejudiced opinion here. No excuse for a car to try to hit anything intentionally, and if the biker had been killed, could have been manslaughter.
