Ads in cars, partnerships with alternative destinations, etc. definitely would feel like enshitification for a demographic comparable to the hacker news one here. But these are all per session/user settings just like most of us have a paid Spotify account and never see advertising and those who don't get a very different monetized experience.
What is exciting about monetization like this is the possibility for rides to become very cheap or even free. If my dentist offers free rides to the office in return for my loyalty, I'm quite happy to take that.
