Older drivers are less likely than young drivers to stop using their cars, no matter how much public transport improves, a survey by motor insurer Privilege Insurance has shown.

More than 40% of drivers aged 17 to 24 would use public transport, compared with only 25% of drivers aged 65 and over.

Inconveniences such as road and city centre tolls, more expensive parking and motorway bus lanes would cause just 30% of 55 to 64-year-olds to give up their cars, compared with almost 50% of the 17 to 24 age group.

Privilege business manager Catherine Alty said the insurer had begun offering drivers aged 50-plus competitive motor insurance, as the company believed they had a more responsible attitude to driving.
