If there's traffic, I'll act like a car and stop also. If there's no one around, I'll just ride on through. No sense slowing down or stopping when I'm in the mall parking lot at some random stop sign.

Traffic lights are the same deal. If no one's around (IE, it's 2:15 am and I'm not big enough to trigger any of the lights around these parts), I'll just ride on through. During the day when there's cars to trigger the lights for me, I'll act like a car and wait.
