UK to allow driverless cars on public roads in January
When ever I see a new place or country allowing a test of these cars this wired article always comes to mind [1].I think the two main questions will be liability & drivability -1) when (not if) these cars get into a serious crash, 
who is to assume liability? Is it Google who created the algorithm? Is it the Audi integrator who fused Google technology into the Audi? Is it the fault of the mapping software that did not update the fact that the signals had been moved to a different position on that street?2) More mundane - will a driverless car be able to drive every single place that a drivered car would? When a flash flood closes down the freeway will this autonomous beast be able to drive on the back road that is normally closed to traffic?Having said that I cannot wait for Cars-As-A-Service where the Cars park themselves & disappear when I don't need them and magically reappear when I do (without humans - Lyft, Uber et al. need not apply).[1] http://www.wired.com/2014/05/the-robot-car-of-tomorrow-might...
