Spent a bit of time playing with traffic and parking. One of the issues with the dominant traffic sensor tech (inductive loops in the ground) is that they can fail in cold weather: frost heaves in pavement sometimes crack the loop wires. In the south, southwest and the pacific northwest the incidence of loops is much higher than in the northeast. There's also more driving, so the incentive to optimize that part of the experience is much higher than say, in the Boston area, where they really just want you to give up the car and use public transportation.
