We don’t half self driving trains because there’s far, far less incentive. You only need 1 or 2 drivers for a huge train carrying a lot of ppl/stuff. Optimizing away the driving barely reduces the cost of operating the train as a whole. With cars, everyone drives themselves. There’s a lot more driving happening and so if you can automate that away, you create more value.
