Continuing rises in the price of petrol could drive some motorists off the roads for good, according to a survey.
As many as 38% of drivers said they would give up motoring entirely within a year if prices at the pumps rise at the same rate as they have for the past 12 months.
An increase of between 14p and 15p a litre would lead to 85% of drivers changing their lifestyles, the survey by car valuation company Glass.co.uk found.
Just 2% of the 2,000 motorists polled felt the current price of fuel was reasonable, with 75% saying it was "out of control" or worse.
A rise of 14p to 15p a litre would mean 10% spending less on food at supermarkets, 11% socialising less and 7% cutting back on spending on clothes.
The poll also revealed that 37% were spending more on fuel than on utility bills, with 70% spending more on petrol than on holidays.
The average amount now being spent on fuel was £102 a month.
Glass's managing editor Adrian Rushmore said: "This research demonstrates that Brits are reaching breaking point when it comes to petrol and diesel prices. Even a small rise will have a significant impact on the majority of motorists.
"We have seen in recent years that demand for high-powered, petrol engine cars is falling due to this. People simply can't afford the current fuel prices and are gravitating towards diesels and more fuel efficient models."
