Drivers may soon be forced to stick to speed limits by satellite technology that automatically slows down speeding cars.

Radical road safety reforms being considered by the European Commission would require every new vehicle to be fitted with a device that limits engine power for anyone driving too fast.

The gizmos use orbiting satellites to pinpoint a car’s position, and intervene if it enters an area with a lower speed limit – such as a controversial 20mph zone – to slow it down.

While Europe’s proposal to make such devices mandatory from 2030 would not extend to Britain because of Brexit, experts say almost all manufacturers would still install the technology in models sold here because it would be too expensive to make exceptions for UK vehicles. And that would make it easier for the UK to intoduce its own legislation later.

The MoS can also reveal that 5,000 of London’s 8,000 buses have already been fitted with speed limiters, with the whole fleet set to be covered by 2031.
