A team at Newcastle University is developing new technology aimed at helping older drivers stay on the road.
Many give up because their reaction times have slowed down – but this means they become more isolated and inactive.
One of the Intelligent Transport team’s developments is a “Granny-Nav” which identifies the safest route, such as avoiding right turns.
The Age UK charity said “ability not age” should determine how safe someone is on the road.
