Not quite. This article is about riders being able to rent cars for their own personal trips. There is a separate flow for partners to be able to rent a car from Getaround to drive for Uber [1], which has been around for about a year.

Uber already has discounted weekly rentals through Hertz, Uber Xchange short-term car leases from select dealers, and Uber Financing where the driver buys a new car from Nissan/Toyota/Hyundai at special pricing with unlimited maintenance included and the monthly finance payment comes out of their monthly Uber check automatically.

I interpreted this as being an option for riders, not drivers.

Yes, even through getaround. Uber does provide this as a service for drivers.

But this announcement is about a rider side product.
