Current bill text: http://leginfo.ca.gov/pub/11-12/bill/sen/sb_1251-1300/sb_129...
What seems to have changed since May:
- The California DMV will set safety rules before 2015 instead of waiting for NHTSA to allow production use,
- The manufacturer must apply to the DMV before production use.
- Cars must record sensor data for 30s before every collision.
What I don’t like about the bill is that it requires an operator to be able to take manual control of the vehicle at any time. I’d imagine that as autonomous vehicles develop in the coming years, this restriction will have to be removed.
