That a boy ha
I was going to say tiny little marbles out the sunroof/window. They'll back off pretty damn quickly.
Up north here we have gravel shoulders not even a foot away from the edge of the road, so take a little swing into that, they screw off
lol, the only problem is that I have found that many people could care less if their car gets hit with pennies/gravel and it just angers them more lol. I'm amazed at how many people out their just don't care about their vehicle/investment.
I've calmed down in the past few years (I think mainly because I often ride my motorcycle as a DD now and don't want to get pancaked lol) and what I normally do now is just get out of the friggin way...people are so crazy...I still can't figure out why people rush to work lol.
I think people don't realize how dangerous they drive until it's too late. I won't even ride as a passenger in a car without knowing whose driving and how they drive anymore.
