he would probably written that crap load of tickets try to cover his a**. Basic drivers ed teaches you not to follow motorcycles too closely because they do stop faster.
The bullying factor enrages me however. Basically, the cop is wrong and he's threatening victim. That's abuse of power.
As far as the biker goes, he never "gunned it". The speeds don't look like they get much above 35. He didn't split lane either. He changed lanes just as the person on the right shifted further to the right. He was driving very defensively ultimately yielding to the car moving into his lane. He shutoff of his bike and was way more civil to the cop than the cop was to him.
