But where are the cars themselves coming from in this scenario? Are these still other people's cars which Lyft/Uber are essentially paying you to put on their platform? I don't think you can afford to pay people that much less than drivers are paid per hour. Is Uber/Lyft taking care of gas/maintenance or is the owner on the hook for that in the middle of whatever else they might be doing? Or does Uber/Lyft own the cars, in which case you've just replaced one big cost (paying drivers) with another big cost (owning a fleet of vehicles)?
