Uber enforces standards on drivers and cars to use their platform -- and take around 30% or more per ride. This is obviously completely different from HN's "Who's Hiring?" threads.
Well, the standards can't be that important. If you post the r-word in your job listing you're not going to get listed. But the payment may do the trick.
But then you have the opposite problem, don't you? Ford or Exxon is making a significant profit from the activity too. The former may even be imposing standards -- some modern cars have a limp-mode if they detect a fault -- and they had a lot to do with whether the vehicle is wheelchair-accessible.
