Scientists in Britain say technology could help keep older drivers on the roads longer, reducing their driving risks and improving their confidence.

Researchers at Newcastle University said they have created an "emotionally intelligent" electric car that can monitor drivers' concentration, stress levels and driving habits.

Scientists said the modified Peugeot car, equipped with a host of devices from eye-tracking goggles to biometric technology to monitor heart rates and cardiovascular health, is a step towards technologies that will improve confidence in drivers over 65 and keep them safely on the road for longer, The Independent reported.

"We have to accept that, as we get older, our reactions slow down and this often results in people avoiding any potentially challenging driving condition and losing confidence in their driving skills," project leader Phil Blythe said.

"The result is that people stop driving before they really need to," he said. "We are looking at ways of keeping people driving safely for longer, which in turn boosts independence and keeps us socially connected."

Statistics from Britain's Department for Transport show there are as many as six million license-holders over 70 on the country's roads, compared with fewer than a million 35 years ago.
