From the outside, things don't seem to have changed much since my last visit.
There was plenty of activity in their unmarked, or rather improperly marked research building. It's pretty obvious what's going on, there's a steady flow of Chevy Bolt EV's with Lidar radars on the top with Cruise Automation logos on the side. But they enter and exit from a garage labeled "Borden Decal Co."
An observation: of all the autonomous vehicle testers, I would give Cruise Automation some bonus points. Unlike Google Alphabet Waymo, these folks are testing under real world conditions. The streets of Mountain View are tame and full of fancy new vehicles and yuppies. CA are in a neighborhood with homeless, hipsters on electric skateboards, double parked vehicles and plenty more.
