It's an exceptionally poor strategy to drop $25k on a new car that only gets 17mpg when your intention is to be a rideshare driver. A purely internal-combustion Civic or Corolla gets twice that. A Prius more than 3x. So do the ones that are 3-4 years old already. And the Prius will probably last closer to 200k miles.

I would guess that the ridesharing companies will buy fleets before they'll pay Chevy Tahoe rates for compact sedans.
