As many as two out of three motorists are planning to change driving habits because of sky-high fuel and insurance prices, according to a survey.
Nearly half (48.2%) say their next car will be a more fuel-efficient model, the poll by moneysupermarket.com found.
Also, 11.4% plan to buy a new car that is cheaper to insure while 8% plan to ditch their vehicle and use public transport instead.
Nearly 12% said there were other factors that would influence their choice of vehicle while 8.4% said rising motoring costs would not affect them as they would look to make cutbacks elsewhere.
Pete Harrison, of moneysupermarket.com, said car insurance prices had increased by 31% in 2010 - or by 44p a day.
He said: "With escalating fuel prices hitting motorists hard in the pocket, I'm not surprised most are looking for ways to drive down the cost of getting behind the wheel - especially when the cost of insurance cover is on the rise too."
The poll was based on responses from 1,750 people.
