Research commissioned by Skoda suggests driving alone is the key to health and happiness.
Its survey of UK drivers, in conjunction with YouGov, found that 60% of drivers claim to be happier when driving alone as they can listen to music, look at the scenery or have time to think.
Gladeana McMahon, one of the UK's leading psychologists, said: 'Driving on your own gives you time to think, whether mulling over issues or remembering good times.'
'Given the hectic 24/7 lifestyles we all now seem to lead, the car has become a sanctuary for us to escape to, away from the stresses and strains of everyday life.'
'Current research also shows that people who spend time reflecting on what they are thankful for became more psychologically resilient. So, if used positively, your daily car journey can be channelled to make you healthier and happier.'
And, according to the survey, if we did have to share a car, Cheryl Cole and Stephen Fry were the top choices of partner, followed by George Clooney and Kylie Minogue.
