Self-driving car prototypes appear to be getting better at negotiating California streets and highways without a human backup needing to intervene.
California regulators released documents Wednesday which report data from 11 companies that have been testing the technology on public roads.
The reports catalog the number of times in 2016 that humans took control from a car's software.
Waymo, as Google's self-driving car project has been rebranded, did the lion's share of testing. It reported driving more than 635,000 miles with 124 safety-related "disengagements"—a notably improved rate.
Though imperfect, the data are the best peek the public gets into the fiercely competitive world of self-driving cars and how the prototypes are performing.
