Actually driverless trains DO get closer and faster. This is why some lines have been automated in Paris for instance, after manual driving reached the limit.

- sandworm101 8y agoSubways in some cities (I'm in Vancouver) do some of this. But they are low speed and are on dedicated track. Trains hauling freight and people between cities have to share track with other types of trains, on irregular schedules. That's what an automated road would look like: not one team of cars but a random collection of vehicles that must somehow share the same infrastructure. The number of vehicles per mile of track would also be exponentially higher than any subway system. Automated train systems are still monitored by humans. When things go wrong humans make the little changes to keep the system going. The computer doesn't decide whether to offload the passengers if a train is stuck, or make them wait for some other humans to fix the train. A team of humans can do this for a subway system with a few hundred cars on a dozen lines, but a few thousand cars on many hundreds of roads is another matter.
