You can go back in time before the invention of the train and find autonomous transportation!!!

People used to own 'vehicles' that were capable of automatic obstacle avoidance and fully autonomous navigation to predefined locations. These vehicles were even capable of refueling themselves, self-repairing minor damage, and even self-assembling new units!!

Occasionally the they would glitch and cause unexpected behaviors, and given the technology of the time, the waste products from the 'fuel cell' would cause problems, but they worked pretty well...

Eventually they were replaced by the non-intelligent automobiles, but they are still the preferred method of ground transport in rocky/uneven terrain, and can occasionally be seen in urban environments during parades, or being used for crowd control.

We called them horses ;)
