I used to ride up to the driver’s window at (inevitably) the next light and try to say something along the lines of “did you know you could have [done something dangerous]?”.
Eventually I decided this was a bad idea. Sure, it might feel good but there’s potential peril. Better just get the plate number and report it.
Remember, the gun people forced PA to extend the Castle Doctrine to cars. It’s legal for the driver to shoot you if they deem you to be a pest.
@Unrealmachine, there are a few problems with that advice. One you have to have your pepper spray always handy. Two, it’s aggravated assault. You may get away with it, or the driver may claim you did it without provocation and you could end up getting arrested. Three, it’s not necessarily that easy to spray someone else without missing, or possibly even spraying yourself. Four, some people are immune to the stuff.
I agree that there are an infinite number of possibilities in the aftermath. A person has the right to protect themselves though without having to pass a litmus test of getting mugged/assaulted/raped/etc. first. Again, I am referring to situations where one feels an imminent threat to their safety is occurring. It might put you in more danger to try to pedal away. As for the driver pressing charges, they will have to explain why they got out of their car and approached you in the first place. Or take your chances that driver won’t attempt to run you over, again.
