Self-driving cars could run on unlit roads to conserve energy

Lights could go out on motorways after driverless cars are introduced, to save energy and end “night blight”, an official report says.

A study published by Highways England said that self-driving cars would reduce the need for lighting because vehicles could be guided by radar.

The report was compiled by a panel set up to improve the design of major roads after John Hayes, the transport minister, said they were “brutal, crass and ugly” and failed to blend in with the countryside.
