Well, our city (far smaller than Shanghai) has installed few devices to monitoring traffic jam many years ago, probably because nobody actually wants to take stand beside a road for a whole day as a carrier. It's very interesting point, but not just because abundant and cheap I think. I was discuss a potential business model with my boss years ago for fun. It's about a breakfast deliver service. My point was, if we have enough data, then we can optimize the process so we can deliver all the breakfasts in the time window (to make sure people can get their breakfasts once they wake up in the morning, and the food itself is still in the "best by" time when they enjoying it) My boss ask me back "Why would you think those delivery staffs cannot figure it out by themselves?" Sometime we just forgot how flexible and intelligence human labors can be, and that level of flexible and intelligence is something current automation still can't bring to the real world.
