I’m all for bike lanes, bump outs, etc. but having a mass of cars congested in the intersections and crosswalks is not safe for anyone. You can have good flow and a safe speed. I’d love to see 21 made more into a pedestrian friendly boulevard. But none of that matters if the light sequence is all screwed up.

Mistimed lights make it worse because drivers run red lights more often and block intersections. If you've ever driven in the city the lights are timed on the avenues to keep you going 30mph. Going faster means you run into a red light so there is no reason to go faster. If there isn't a ton of volume you can easily ride green lights for 20-30 blocks if not more.
