I'm testing an embeddable Tweet here. Yes, I realize this is exciting stuff. Some may even consider it mind-blowing. Anyway, the link in the embedded Tweet is fascinating.
Here's my favorite paragraph:
Traffic control: if we have metre-level resolution in our monitoring, we can not only optimize our vehicle and pedestrian traffic flow (to the extent possible, within the hard limits of routing algorithms), we can also handle emergencies more effectively. A six-year-old chasing a ball towards a street may result in the local nodes notifying the autopilot of an approaching car to apply the brakes before the child runs out from between the row of parked vehicles ahead. Alternatively, automated vehicles can be diverted away from potential congestion choke-points before they develop, rather than blindly following a route in a map database.
