Today’s the day: Waymo’s unlikely partnership with Uber is now live in Austin, Texas. The former rivals have joined forces in the hopes of accelerating the transition to autonomous vehicles, and as of today, any Austin resident with a desire to take a trip in a fully driverless robotaxi can open their Uber app and hail away.

Uber and Waymo on Tuesday announced residents of Austin can now order rides with self-driving cars. According to a press release from the ride-sharing service, starting Tuesday, city residents can be matched with an autonomous vehicle (AV) from the Alphabet-owned Waymo company.

The Alphabet unit starts commercial operations in its fourth city, where rides can be booked with Uber’s app. Uber is also providing charging and maintenance services.
