In DC, yellow means go faster, so yeah it happens.
I'm pretty cautious personally, only because there are red light cameras everrrrrrywhere now.
Totally DC is the WORST, worse than NOVA IMHO. People blatantly run them all.the.time. People will go through it until the cars start moving on the next road. As a pedestrian, it really makes me fucking pissed.
I don't know how any city would function traffic-wise without left turns on red. 1-2 cars that pulled into the intersection during the green though, not 5-6, which I have often seen.
