I think the main obstacle to the deployment of such systems is not technological, but societal.

On 4 November 2011, 34 vehicles were involved in a collision on the M5 motorway, resulting in 7 fatalities and 51 injuries. This incident received a lot of press coverage at the time. A total of 1,901 people died in road accidents in Great Britain in 2011 [2].

Can you imagine if the 34 vehicles involved in the collision had been automated? There would have been a public outcry and demands for the system to be withdrawn from service.

The aviation authorities require that UAVs be as safe as a manned aircraft, which is a creditable aim. It seems to me that unmanned automobiles that were "only" as safe as an equivalent manned automobile (i.e. that caused 1,901 fatalities each year) would not be acceptable to the public (who would refuse to ride in such "unsafe" vehicles) or to engineers (who know that we can do so much better).
