James, it is difficult to argue with figures that have legitimacy and statistical validity,and I feel that UK studies show similar results.However in my opinion the statistics and the colours have no regard to the idiot behind the wheel?
A dark colour remains difficult to see in poor visibility when the driver fails to observe the requirements of the Highway Code and fails to switch on his/her lights.Until recently DLR`s did not light up the rear of a vehicle.Many drivers were oblivious to this fact. Many drivers do not switch on lights in poor conditions , early in the morning or at dusk.Dipped headlights are required when driving in the rain, etc.
Volvo piloted studies years ago which led them to fit day driving lights as standard on their vehicles, because a lit vehicle could be seen by an oncoming driver in a fraction of a second than would otherwise have been the case..
If all cars on the road were white you would still have roughly the same number of accidents as you would have the same number of idiots behind the wheel
