Driverless cars bringing a boost to commuters' productivity is a long way from reality as British motorists are still wary of giving up control, a study has found.
More than two thirds of UK adults surveyed said that they would not attempt "any activity in lieu of driving" in a driverless car.
The survey by the University of Michigan said that "36 per cent would be so apprehensive in such vehicles that they would only watch the road," while travel sickness would prevent a further 10 per cent of users from being able to use mobile phones or laptops.
Such concerns mean that we are further away from seeing fully autonomous cars on the road than many people expect, a separate study suggests.
The Centre for Future Studies suggests that driver aids such as cruise control and lane assist lead the general public to believe that driverless cars are a few years from being a common sight. However, Frank Shaw, foresight director of the centre, said: "We are saying that is more likely to be in the 2040s and, even then, there will be plenty of cars on the road that will need to be driven."
The study, which was commissioned by Kia, concludes that it will take until the 2040s for satellite-guided electric vehicle to account for 50 per cent of new vehicle sales and make up 30 per cent of all cars on the road.
