I'm incredibly hopeful that NYC congestion pricing pays off in a big way - and that we start to see it in other cities across America. I really, really want congestion pricing in downtown SF. During rush hour, cars block the box and slow down busses, with cascading effects.
There's an easy solution to this: have ticket writers waiting at intersections to paper all the cars who do it. It's not like they can drive away. NYC used to be really good about enforcement, and it worked extremely well.
It doesn't solve traffic, but it does help stave off gridlock and keep intersections free for bus lanes to operate normally.
