From The Times:
All new cars will be fitted with devices that make sure they automatically keep to the speed limit in a move billed as the biggest overhaul of road safety in more than 50 years.
Within the next three years, models sold in Europe are expected to use technology that detects limits and slows down vehicles travelling too fast.
It will be one of 15 new safety features fitted as standard to cars, HGVs or buses. Other measures include technology that detects when drivers are losing concentration or falling asleep, a system that keeps cars in the centre of lanes and accident black boxes that record vehicle movements.
All cars will also be fitted with automatic emergency braking, which brings vehicles to a stop when pedestrians step into the road or a car ahead suddenly slams on the brakes.
The measures were approved by the European Commission and are expected to be rubberstamped by the European parliament and member states in September. The UK government has already said that vehicle standards will be aligned with those in the EU after Brexit, meaning that the same rules will be expected on British roads.
