I thought this whole sensor thing a lot in the past, specifically as an argument to criticize the state of our autonomous vehicle development. We must be very careful handling electronic failures and sensor reliability. I know someone will bring up "well, traditional car will fail and results in fatal crash too, but technology can help us catch that and predict accidents by looking at 360 degree!". True, but let's not let that promise blinds us. Also, this senor-led, slot-based system won't work in areas like NYC midtown, so not a one-size fits all solution (that's a given). If we exclude accidents and roadworks, then traffic lights, narrow roads, increase of cars on the road (due to ride-sharing and cars becoming more affordable), and double parking, they all contribute to the majority of traffic jam. Some futuristic fixes include flying cars, roads in mid-air, roads through buildings, and more underpass might help but they don't scale when you keep adding more cars. We need to improve our mass transit. If you have ever played Skyline or SimCity, you know that intersection sucks and mass transit is preferred over roads. Too many school buses will slow down traffic. Multi-lane to single-lane can jam the road. The NY subway system coverage is pretty good, but each train runs on one lane and is a single point of failure. Kudos to those working in transportation planning though...
