Although GM has already invested $500 million in Lyft and has a $99/week program to rent cars to drivers on that platform, it seems the carmaker isn’t interested in playing favorites: GM has now teamed up with Uber to offer a car-sharing program for its drivers as well.

Uber will be partnering with GM’s existing car-sharing company, Maven, which launched in Germany and the U.S. early this year, Recode reports.

Uber drivers in San Francisco will be able to rent a GM vehicle — the Chevrolet Cruze, Malibu, or Trax — for $179 a week plus additional taxes and fees, GM says. The pilot program will only last 90 days.

“We want options that fit around [drivers’] lives,” Rachel Holt, Uber’s General Manager of the U.S. and Canada, told reporters during a press call.

So what about any potential conflicts, you know, what with GM also partnering with Lyft for its Express Drive program? Lyft says there is no threat to its business with this partnership, because Lyft is also working with Hertz to rent cars to drivers.

“Maven’s supply channels do not impact our programs with GM,” a Lyft spokesperson told Recode in a statement. “We continue to work together to shape the future of mobility.”
