It looks like the car tried to knock over the motorcyclist in retaliation for kicking his car, over compensated, and lost control.
Knock a motorcyclist over at highway speeds? That's tantamount to attempted murder using your car as a deadly weapon, basically.
This is why I quit riding. Some cars are just murderous ass holes. Is ass holes one word or two? Is it a type of hole, being of the ass variety, or a thing in and of itself, like an asshole?
