I got my first bike/motorcycle in 1963. I found out over the years that sometimes cars don't see you, or can't see you, or don't understand what you can, and can't do concerning the bike.
But I also learned that there is a difference between those that ride motorcycles, and
bikers.
I learned that when riding a bike, that I had better pay attention to everybody around me. I learned that
bikers DEMAND that you pay attention to
them.
A little mistake that amounted to nothing, will be blown into a confrontation.
Working on the sales floor for a big Harley Davidson dealership I saw this
attitude almost daily.
I have no idea what the driver of this car did, or perhaps didn't do, or if the driver was male, or female.
BUT! It's quite obvious what the
biker was doing, or at least, trying to do. He could have blown whatever angered him off, and rode on to the house. But he didn't.
Maybe the driver got sick of threatening, maybe he didn't like
bikers, maybe he, or she was scared of the
bikers aggression.
Whatever the reason, a 750 pound bike, is no match for a 4,000 pound automobile
