Research has found drivers are regularly speeding on the UK`s roads to try to beat the journey times predicted by their sat navs.
According to a survey by Autoglass, drivers under 25 are the most likely to be reckless racers, with 26% admitting they nearly always challenge themselves to beat sat nav times
A further 17% of drivers aged 17-18 year olds said they had got penalty points on their licences for trying to outdo the sat nav times.
The findings show that two in five of the 3,000 people who responded regularly exceeded speed limits to arrive sooner than their sat navs had predicted.
The worst offenders were in Aberystwyth in Wales and Wolverhampton, but "sat nav racers" are also a problem in London, Oxford and Worcester.
Autoglass managing director Nigel Doggett said: "Exceeding the speed limit is a serious offence putting the driver and other motorists in extreme danger on our roads.
"A sat nav takes into consideration the speed limits on our roads when calculating a driver's estimated journey arrival time and should be used only as a helpful navigation device. Safety for UK motorists on our roads is paramount."
