But a few words of wisdom for bicyclists: just because you're not in a car doesn't mean you can ignore all traffic laws. You know those traffic lights in the middle of intersections? When they're red, you're supposed to stop. I nearly had to scrape one of you off my bumper earlier this evening when you didn't stop for the light, and I (naively) thought I could proceed through the intersection with my pretty, green light.
And you know those hand signals we learned when we were kids? The ones for left and right turns? Try using them. Those of us in our four-wheeled vehicles might have a clue as to what the hell you're doing.
