Road tests for robot cars?

Vast sums of money are being devoted to developing self-driving cars. To date, licensing requirements require that self-driving cars have a licensed human driver at the wheel able to take over from the machine — thus negating most of the potential value of the technology. Technical progress has been rapid, with cars increasingly able to drive themselves at night and in bad weather. It is therefore now time for policymakers to identify the criteria under which they would allow self-driving cars without humans at the wheel.
