I'm skeptical of this. Something as simple as knowing the meaning of curb painting color, turning on red, or knowing when to move past an emergency or other special vehicle requires non-universal knowledge of regulations, sometimes hyper-local. The idea that nothing they do would be affected by country-specific regulations is dubious.

so they can't induce movement of the vehicle, at all, ever?

that's probably fine then

but if they can at all: they need a driving license

it is not unreasonable for a state to want to control who is allowed to move around 1.5 tonnes of metal in a public environment
