Young people are much better than elderly drivers at taking on board the message about making fewer journeys by car and more using public transport, research suggests.
A report from the RAC Foundation found there had been a drop in the number of car trips taken by 16 to 29-year-olds over the past 10 years.
But research showed a rapid growth in car ownership and car usage among those aged 70 or more during the same time period.
The report, produced for the RAC Foundation by a team of leading transport academics, found drivers aged 30 to 49 used their vehicles the most - travelling by car for 69% of all trips taken.
Lead researcher Dr Karen Lucas, from Oxford University, said the number of licensed cars had grown from 22.7 million to 29.6 million in the last decade - a rise of 30%.
About 8% of all trips under half a mile are taken in a car, while this figure rises to 78% for trips of two to three miles, and 80% for trips that are five miles and over in length.
Dr Lucas added: "Our research suggests that most people cannot envisage a future without their cars and many would go to considerable lengths to continue using them."
