That’s not something the average person off the street is going to ask. But many are going to be pissed learning they will reimburse you for paying someone to clean your car but not the time it takes you to do it yourself, nor the lost wages until it’s clean.
But taking the outside view, you don't need to know all the specifics. You can just check Uber's general reputation (or lack thereof perhaps) for fair dealings with drivers. That general reputation will reflect how they are dealing with those edge cases in general.
Just like in the 2010s you could be reasonable certain that a job at Google meant you got free food, even if you didn't know the exact specific rules about what food would be available when and where.
If people get a worse impression than reality they can release more information, but if the public has a better impression than reality then they have zero incentives to say anything.
Or they could keep pissing off the people with the monopoly on violence, maybe that'll work long term?
What changes is the information asymmetry where Uber etc knows a lot more about the conditions of people working for them than the people taking these jobs do. As a general rule those with more information are simply in a vastly better negotiating position.
