LH...I moved to DC in 77 from Kansas and thought it was bad....it is a LOT worse now. In certain areas and at rush hour it is...well, we OFFICIALLY have the 2nd worse traffic in the US. Various reasons...geography, growth..etc. A few things have been improved...like the I-95/I-495 interchange and the bridge over the river. And Metro keeps a lot of people off the road.

One simply does NOT trust that the rules for yellow/red lights will be observed....and it's best not to assume that if YOU slow for yellow, that those behind you will.
