Except that Google was able to handle construction sites, traffic cones, and people directing traffic last year. Watch Urmson's video from SXSW.[1] Google has put a lot of effort into handling unusual situations. Those cars driving on residential streets in Mountain View and Austin have accumulated data on the hard cases.

The California DMV continues to publish autonomous vehicle crash reports. The last one was in October.[2] A Google vehicle was rear-ended at 3mph when it was entering an intersection with poor visibility, detected cross-traffic, and stopped.

I'm looking forward to the 2016 self-driving disengagement reports appearing on on the California DMV site.[3] Those were due January 1, covering the year ending 1 December 2016. Then we'll have comparative info on how all the players are doing.
