A good illustration of why autonomous EVs will stop trains in their tracks. Tracks are expensive, precise and single-purpose. A road is cheap, flexible and multi-purpose. Being tied to the grid means you can't go where you need to get to, only pre-set destinations. And since every train-car can now drive itself, there's no longer a need to tie them together, so instead of 5 cars bunched up all at once every 10 minutes, you can get a single car every 2 minutes. That is, once this tech matures, no new train development will make sense.
