Speed-limiting devices that could be fitted to thousands of cars will not prevent as many accidents as the Government claims, a motoring group has argued.

The Association of British Drivers (ABD) accused the Government of using misleading statistics to underpin its 'war on drivers', and said claims that intelligent speed adaptation (ISA) could prevent up to 29% of injury accidents on the roads were bogus.

According to the ABD, this figure comes from two entirely different factors that could contribute to fatal accidents: 12% for exceeding the speed limit and 17% for 'excessive speed for the conditions' – but still driving within the speed limit.

Inappropriate speed

'Clearly ISA cannot control inappropriate speed under the posted limit and the 29% claim is therefore demonstrably bogus', an ABD spokesperson said.

'ISA may well result in an increase in injuries on our roads because it could encourage 'foot to the floor driving' in the knowledge that the speed limit cannot be exceeded, and sends the wrong message that the speed limit is always the safest speed to drive at.'

The ABD also raised concerns over the Government using the GPS technology to track drivers' movements in the name of road safety.

But the Commission for Integrated Transport (CfIT), the pressure group that released a report on the effectiveness of ISA, said it has real safety benefits and that using it could cut CO2 emissions by up to 6%. Under current plans, drivers will be able to choose whether they adopt ISA.
