TweetSorry bro, did not see it. I would say I am not going to chunk something or use a "get back" whip. Not wise to throw a piece of spark plug ceramic while riding.
Just wait for em to pull up to a light and smash their mirror down with your fist, it will break off with little force in most cars. Not that I have ever done it but I have seen it done before. Lady pulled out into a toy run as she did not want to wait until we passed. She got both her mirrors busted off and possibly other damage. I rode away as I did not want any part of that crap.
my best offense is staying away from cages as much as possible. (not possible) but on the freeway I can pick my spots and keep moving through traffic. if one sits at a constant cruising speed people will tailgate, (and it is dumb to brake check a car on a bike) pull into your lane, hit their brakes hard.
People in cars are dumb when it comes to bikes. My little enduro does not have enough power to "stay in front" I have to be real careful. the big bike I can slice traffic like a razor blade.
