When the Hertz rental car company announced it would buy 100,000 Tesla Model 3s in late October, it was the biggest single order for electric vehicles ever.

But just a few days later, Hertz CEO Mark Fields said he might double the order by 2023 and make as many as 150,000 of those Teslas available to Uber drivers through a program that launched in Los Angeles, San Francisco and San Diego on Monday.

Five things you need to know:

  1. Up to 50,000 of the Tesla Model 3s Hertz ordered last week will be made available to Uber drivers.
  2. Uber drivers who have given at least 150 rides and who have a rating of at least 4.7 stars are eligible for the program.
  3. Model 3 rentals for Uber drivers cost $334 per week and include unlimited miles, maintenance and insurance. The only additional cost drivers incur is charging the vehicle.
  4. Uber drivers can find and book Teslas from Hertz through Uber's Vehicles Marketplace in the Uber driver app.
  5. Uber drivers who rent Tesla Model 3s through Hertz will earn an extra $1 per trip.
