As a cyclist, every day to work, you both missed one issue issue of the red lights, sure there is the momentum issue but there is also a safety issue. When you go through the light you are out of sync with the cars and by yourself, this reduces the chances for the dreaded right cross and all sorts of other car mistakes. I run reds because I feel safer doing so, no law changes will be able to change that, only road improvements... Thanks for the great discussion. Brian
