Uber is working to get its self-driving cars back on the road in California.

The ride-hailing company says it's currently running two Volvo self-driving cars in San Francisco in manual as it prepares its application for the self-driving testing permit. That's in addition to the mapping cars, which have been back in California since January.


Uber then argued in a conference call with reporters that its cars are more aligned with electric car maker Tesla's autopilot feature — an advanced driver assistance system, but not a car that's fully autonomous — to again make the point that these self-driving permits weren't applicable to its technology.
