A survey has found that owners of big-engined cars are the big bullies on the road, while motorists driving small vehicles are calm, courteous and considerate.
According to the poll from the Fuelcard Company, the large-engined car drivers were least likely to let other vehicles to pull out ahead of them at busy junctions, with men being three times less likely to let others ahead than women.
The survey of 1,600 city centre motorists also revealed that 47% of big-engined car drivers did not stop at designated crossings.
Motorists of the larger-engined cars were the worst at jumping lights, tailgating and showing a lack of consideration for pedestrians.
Drivers of the BMW 3 Series, Audi A4 and SUVs were the worst offenders, while drivers of SmartCars, Fiat 500s and Volkswagen Polos were the most courteous.
Jakes de Kock, marketing director of Fuelcard Company, said: "City driving can add extra pressure to a motorist's journey as drivers are more likely to encounter high volumes of traffic and congestion, resulting in defensive driving techniques.
"Aggressive driving is not only dangerous but can actually increase fuel consumption by as much as 40%."
