Autonomous trains > autonomous cars. Czechia launches the first European autonomous passenger train on a local branchline: https://english.radio.cz/czechia-launches-europes-first-driverless-passenger-train-8847581

For now, there still needs to be a driver on board, but the plan is to eventually make fully autonomous trains. Especially for less-frequented routes (which Czechia has a lot of), it could help with making the frequency better without breaking the bank.
