It's also a general rule not to look at someone, or even smile when next to someone at a red light, there are alot of questionable people living here, and I've had a gun pointed at me because me and a friend were laughing at a stop light about what his g/f said the night before... About 7 25yo guys in a 5 seater olds beside us...Guy beside says "You think somethings funny, gotta problem with my car, think my spinner caps aren't tight enough yo" and then he pulled a gun and we took off, unfortunately we were in my friends hyundai 1.3L (or something) Scoupe... luckily his Scoupe is turbocharged and modded. We ended up getting away by out handling them in some residential areas. So i've learned to not acknowledge most other people while im driving.
