There’s an old joke that I’ve heard in the context of Boston driving, but likely gets recycled for different locales:

A yellow light means speed up.  A red light means two more cars.

Today when I was driving in Detroit I pulled up to a make a left turn and saw the light had turned yellow.  I accelerated through the light and the intersection, knowing that I was cutting it close.  I might have even seen the light turn red out of the corner of my eye.  I couldn’t help but laugh to see the two cars behind me continue through the red light and across the intersection (in front of two lanes of traffic).
