Some young drivers are "playing a dangerous game" racing to beat the estimated time of arrival (ETA) on their sat nav, the AA has warned.
In a survey of AA members carried out by Populus, more than one in 20 (7%) drivers aged 18 to 24, and 8% of those aged 25 to 34, said they view the ETA on their sat nav as a target they try their best to beat.
Overall, just 2% of drivers said they race their sat nav.
Young drivers (9% of 18 to 24 year olds and 7% of 25 to 34 year olds) were also least likely to say they were not interested in the ETA and only used a sat nav for navigation. This rose to 19% among the over-65s.
The findings come as changes to the driving test mean that learners will have to show they can follow a sat nav responsibly during their test.
Other additions to the driving test from this week include an increase in independent driving, new reversing manoeuvres, and answering a vehicle safety question whilst driving.
"Technology is always changing the way we drive and the development of in-car systems like sat navs mean drivers must learn how to use them safely," said AA president Edmund King.
"We know from our driving school that young drivers are keen to get the most from the technology available to them and these changes to the test will help ensure they do so without it adversely affecting their safety."
However, King added: "Racing your sat nav is a dangerous and futile game. The best pace to set for your journey is the one that gets you, and everyone else on the roads, there in one piece."
