Uber will shift into a new gear in Austin, Texas, on Tuesday when its ride-hailing service will begin dispatching self-driving cars to pick up passengers. The autonomous option is being provided through a partnership that brings together Uber and robotaxi pioneer Waymo,

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.

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.
