Well, see, if you've got a red arrow, you know you're gonna get a green arrow when the time comes... What I really love are green right turn arrows. I hate stopping or knowing I'm illegally rolling through stop lights with the other traffic is turning left and blocking all the other traffic...

Try driving in san francisco sometime. Half of the signals on some hills are for street cars. I don't know if i'll ever be as baffled as I was the first time I encountered a red 'X' signal.
