Should we also have a transportation worker's bill of rights, that sets the reasonable output that one can expect from a human? Would it be reasonable to set that rate based on what a human can deliver on foot, unassisted by any vehicle?
The whole point of a tool is that it increases the amount of output we can expect from workers. Otherwise we'd still all be doing agriculture, because the farmer's bill of rights sets the maximum output of a farm and there's not enough surplus for non-farmers.
We do have a transportation worker's bill of rights. The vehicles may not tire but the drivers do, and therefore all truck drivers are entitled to mandatory rests. And self-driving cars (current ones, at least) have a similar issue: because the driver must be prepared to take the wheel at all times there's a whole bunch of "increased output" that they're not allowed to take advantage of, with a risk of serious jail time if they do.
IMO the key is risk: right now no one is taking responsibility of the AI errors (IMO by design), but the second we codify who's legally responsible for them we'll see calls for slowing down coming from those groups.
