I do know that it is near Impossible to RAM a moving car on my motorcycle and continue to keep following them. But if any one says this can be done I'd love to have a lesson, please provide video.
and
anyone that believes the rider 'rammed' the auto isn't very intelligent, this very likely could not happen without the bike going down.
First, my bona fides: 65,000 motorcyle miles, including two cross-USA trips and one training day at the Keith Code Superbike School during the mid-1980s.
Second, it depends on what you mean by "ram." If you mean smacking the front or rear of the bike into another vehicle, that action would likely be very bad for the biker because the front or rear wheel would contact the vehicle. For that reason, I think "ram" is being misused. Instead, it was probably some sort of side contact.
I once had a car drift into my lane and smack me. Due to the gyroscopic action of the bike's two wheels, I was not knocked down. Actually, I was shoved about 6 inches to the side, and my footpegs scraped the paint on the car's side.
I very seriously doubt the biker "rammed" the girls' car. More likely, they cut into his lane because they weren't paying attention (like what happened to me), thought they had damaged "Daddy's car," and claimed the biker had rammed them so Daddy would get angry with the biker, not them. The biker probably got P-O'd and followed them to give them a piece of his mind. When he saw Daddy outside with the gun, the biker probably figured he'd best leave, and then Daddy shot him in the back.
The above would be my hypothesis until I learned more facts.
