I think I'll wait for the dust to settle a bit here, since it's hard to tell what happened. This is the wreck photo from the local news, showing a damaged bike on the sidewalk, and an Uber robo-car with front passenger-side damage, sitting in the right lane:

It's hard to square that with someone darting over from a brushy median on the driver's side of the car. Hopefully NTSB will grab the sensor data and sort things out.

EDIT: This could get ugly...

tl;dr -- A homeless woman was walking her bike across the road. "Safety driver" of the robo-car may have a record for attempted armed robbery. Uber disputes the driver's identity.
