The survey of 350 motorists found that among drivers of black cars, 47% admitted to road rage when under stress, and proved to be the first to admit defeat, with 30% wishing they had stayed at home rather than venturing out, compared to only 8% of white cars.
Michelle Murphy, of Trafficmaster, said: 'Those with the worst journey experiences tend to be those that don't plan and prepare their journey properly – half of those driving black cars admitted doing nothing to avoid traffic for example.'
Black car drivers are the most likely to get lost on holiday (63%), and need to drive to hospital (27%) during time off from work. Drivers of green cars are the most likely to resort to aggressive driving when stressed (25%) and to shout at fellow passengers (20%).
Drivers of silver cars are the most relaxed.
