....Oldham drivers 'most intelligent'

Drivers in Oldham are the cleverest in Britain, but those in Rochdale are the least bright, a survey has suggested.

The eBay motoring intelligence test also found Bentley and Aston Martin owners have the lowest IQ, with classic Triumph drivers scoring top.

The survey assessed drivers on their knowledge of facts including stopping distances, speed limits and road signs.

Results were based on 6,000 responses from people in 100 different towns across the country

Researchers found that half of all drivers did not know basic rules such as minimum stopping distances.

One sixth of respondents could not identify simple road signs, while 5% did not know the motorway speed limit.

Formula One racing driver David Coulthard took the test and scored 34 which put him in the motoring genius category, eBay said.
