I think it's fair to assume that driver's want to be paid at least fair wages – or at least that they don't wish, all other things being equal, to be underpaid.

I think it's fair to assume that driver's want to be paid at least fair wages – or at least that they don't wish, all other things being equal, to be underpaid. Now, whether or not Uber/Lyft can actually provide that to a degree that the CA legislature finds acceptable while still being a sustainable business is the question. If drivers are required to comply with Uber's policies or choose not to drive for Uber, then it's not unexpected to require Uber comply with US / State labor laws or choose not to operate in the US / state. Legal specifics of what "comply" means in this case is up for debate, which is ultimately the court's jurisdiction – or in the case of Prop 22, the people at large – to decide on behalf on all parties, not Uber's and not even the drivers themselves.
