I posted recently about Lyft’s program that offers drivers in three cities free rental cars when they drive a certain amount of rides per week.

Now San Francisco drivers can get in on an even better version of the offer: Free electric vehicles, which could drastically reduce the gas expenses for drivers.

Lyft announced today the addition of Express Drive to the SF market, adding that LA and Denver will soon follow. Lyft says drivers will have access to the 2017 Chevy Bolt EV and 2016 Chevy Volt.

The partnership between Lyft and GM has been beneficial for drivers so far, but that could reverse in the future when GM starts funneling self-driving cars to Lyft.

I’d love to hear your thoughts. Have a good day!
