How are tunnels pointless in a future of self driving cars, the opposite is true, tunnels make even more sense when cars drive themselves.

How are tunnels pointless in a future of self driving cars, the opposite is true, tunnels make even more sense when cars drive themselves.
- ben_w 6y agoSelf driving cars done right will be able to do full speed while literally, not metaphorically, touching bumpers. Traffic jams with human drivers happen spontaneously when the cars get close enough that overcompensation turns into a negative spiral.
- nickik 6y agoSo in the city of the future you gone have 1000s of self driving cars going full speed threw the city? It makes much more sense to open up the city for people and ban cars for the most part. Move the transportation under ground.
- ben_w 6y agoPlease, millions. The roads are already there, electric cars are quiet, road trains are even more efficient. I am no fan of American city design, having half encircled Davis CA on foot, having found the suddenly-terminating sidewalks in Salt Lake City, and having walked the really boring route from San Jose railway station to the hotel in the top left corner of the Apple Maps icon. (NYC is surprisingly pedestrian friendly though).
- nickik 6y agoIn Europe we are already trying to make more space for pedestrians specially around the city center. The value of the land above ground is incredible. Freeing up those spaces from cars makes sense and is incredibly nice.
- ben_w 6y agoI know, check my profile ;) But: 1. Musk doesn’t live in Europe, he set up TBC while stuck in a traffic jam in Los Angeles. 2. Solid car trains moving at full speed (whatever that is for the road, 20 kph for residential or much higher than the current rules for highways) use less land area than any other traffic, so some lanes can become bicycle only or whatever. 3. They can “perfectly” obey traffic lights and give way to pedestrians 4. Raised walkways are cheaper than tunnels
