Yeah, I have noticed this. Red lights, I'll admit, could be treated like stop signs and there wouldn't be many problems. That is, if you're sitting alone at a red light it wouldn't hurt to go through it if there is no cross traffic. Though, not wanting to wait seems immaturely impatient for no real gain. The other laws, however should be heeded.
A couple months ago I got hit by a car at an intersection when I was on my bike. Instead of stopping behind the sign and crosswalk area, the driver of the car thought it would be a good idea to run me the f**k over. Ok, there was no real damage except for that to my bike and a weak/sore thumb joint for a few weeks. Still... if I had had a stop sign for me, on my bike, I would have stopped because I'm not, well, a complete ignoramus.
