They could keep track of people as best they can, and shadowban them from all transportation using Greyball so the people couldn't function in society. It'd be kind of like getting blackballed for life from credit card issuers. Effective to the extent they can make a monopoly, probably more effective when it's a shadowban rather than explicit rules stating the person is barred from using the service forever.

It would be rather profitable to be able to hold the world hostage, single out whoever you want and make them hoof it. Particularly if they'd got used to using Uber to get to work or something. Long game would be making private vehicle ownership illegal, but that's very long term indeed. I'm just saying, you can keep going and every step of the way is increasingly profitable. Wall Street would love it.
