It's a busy time for self-driving pioneers in California.
On Wednesday morning, Uber brought its self-driving cabs to San Francisco after testing them in Pittsburgh.
For the beginning of this test run, the "self-driving" cars will have two humans up front: one behind the wheel in case of emergencies, and one riding shotgun and collecting data, Recode reports. The self-driving cars are modified Volvo XC90s.

This could be legally hazy for Uber, since it doesn't have a permit the California DMV requires for autonomous cars. But since a human is needed to monitor the car, it might not qualify as autonomous, based on DMV rules.

Meanwhile, Google announced Tuesday it was renaming its self-driving car project to Waymo. The self-drive program is still part of the Alphabet parent company.
We're not in the business of making better cars. We're in the business of making better drivers.
Waymo CEO John Krafcik said the company had racked up three million miles of road testing, in addition to one billion miles of simulation testing.
Waymo is testing its sensors using a Chrysler Pacifica. Tech chief Dmitri Dolgov said the programming was still struggling with bad weather.

Here's a clip of Waymo on the road.
