Uber’s autonomous cars drove 20,354 miles and had to be taken over at every mile, according to documents

Recode:

Some of Uber’s self-driving cars aren’t driving as smoothly as the company hoped they would. Documents circulated throughout the company’s self-driving group, which Recode obtained, gives us a first look at the progress of the ride-hail company’s robot cars in Pennsylvania, Arizona and California.

The top line: Uber’s robot cars are steadily increasing the number of miles driven autonomously. But the figures on rider experience — defined as a combination of how many times drivers have to take over and how smoothly the car drives — are still showing little progress.

Our future full of autonomous cars may be further away than the “experts” think.
