This may be the most important thing you've ever posted on these forums.
It applies to pedestrians too. In grad school I knew a girl that would walk into crosswalks on campus, even if there was a car that was clearly speeding towards it down the road. I've seen the situation several times where the cars would hit their brakes hard because she was in the crosswalk. Her logic was that it was her right of way. Yes. The cars were most definitely speeding, and a pedestrian in a cross walk always has the right of way. HOWEVER, I'd rather be alive and lose my pride than be right and be dead. I remember she totally gaffed at me. Yeah, ok, you go ahead and tell the driver you had the right of way when their 2 ton SUV plows into your 120 lbs body, as they fumble around on their cell phone. Again, the best rule is to always assume the other driver is distracted or a moron in general.
