Google's driverless cars hit the headlines and the public consciousness in May, when the search giant announced a new design. The technology, however, is very much at the prototype stage, with sensors and equipment costing around Â£90,000 over and above the cost of the vehicle itself.
In San Francisco, for example, the hybrid cars will cost $5 for the base fee, and then $3.25 a mile after that. By contrast, the town cars cost $8 for the base fee and then $4.95 a mile.
