Pony & trap could be largely self-driving, after an initial training period. That would have been a distinct negative to "upgrading" for some, I'd imagine.

It's speed and load capacity vs self-driving.
If we could imagine wiring a pony to control a car, its brain, while good at navigation, would likely be inadequate at the speed that a car attains.
