The survey, carried out by ClickMechanic, found the average driver travelling at 80mph on a motorway pays an extra £3,064 in fuel over a lifetime compared with a counterpart travelling at 60mph.

It’s not just their wallet the driver will be hurting, but also the environment. The limit-busting motorist will also be adding an additional 5.67 tons of carbon emissions.

Based on a typical Fiat 500 and a fuel cost of £1.20 per litre, a UK driver will spend an additional £482 on fuel over their driving lifetime by just increasing their speed on the motorway from 60mph to 65mph.

Increasing by 5mph at higher speeds has even more costly consequences. Driving at 70mph triples the extra cash to £1,491 over a lifetime.

Leaning even harder on the ‘go’ pedal will see fuel costs jump to an extra £3,064 over the driver’s lifetime.

The incremental impact on the environment can be seen in the following table.
