More than ever before, motorists are ditching the traditional map and using technology to navigate themselves around the UK.
New research from Halfords reveals two out of three motorists (68 per cent) admit to using sat navs for journeys they do every day, such as commuting to work or going to the shops.
Amazingly, more than a third rate the device as a more important in-car feature than the radio.
The survey also found more than half of drivers (52 per cent) are unable to remember any prominent landmark on a journey, and almost a third (31 per cent) can't recall the name of the road they have just travelled on.
Britons also appear to have lost any sense of judging distances, with 70 per cent saying they use their sat navs to predict their arrival time, rather than check how many miles the journey would be.
Geography was another weakness exposed by the survey as motorists are unable to recognise points of the compass. 61 per cent didn't know Leeds was to the North of Sheffield and 56 per cent failed to say Edinburgh was East of Glasgow.
Jon Oliver, Halfords In Car Technology expert said: "The survey demonstrates how much we rely on sat navs; they have literally changed our lives and drivers now need this technology to navigate effectively.
"Drivers like sat navs because they are so helpful - they take a lot of the anxiety out of driving because you always know where you are, how far you have to go and how long it will take. This leaves motorists free to concentrate on the road and have a less stressful and safer journey."
