“Arkansas linebacker faces felony charge”. It’s hard not to get angry when a cager endangers you or your scooter, but it rarely pays off to fight back. I’ve had a gun waved at me for flipping off a dude that almost killed me, another guy I flipped off tried to run me off the road once, then chased me for blocks (documented in a comic in 2sb issue #3), and a friend of mine was even stabbed by a cabbie once.
Still, the most upsetting confrontation I ever had was with a guy in a van, who nearly hit me. When I pulled up next to him and started yelling obscenities, he was nearly in tears, and said “I’m a motorcyclist, too, that could have been me!” Most of us are cagers some of the time. Drivers are generally sorry enough without us getting in their face, and if they’re not, they’re just going to get even more dangerous when confronted.
Another tip, if you do get in a near-accident, or a shouting match, pull over and calm down, riding while you’re jittery and overfocused on what just happened will just increase your odds of something worse happening.
