SIR - When are we going to face up to the main cause of death and injury on our roads - our lax attitude towards speeding - and put an end to it?

 Rapping someone lightly across the knuckles merely confirms the belief that speeding is not a serious offence unless someone is killed or seriously injured as a result. 

Motorists - and not just celebrities - need to be deterred from speeding before they cause a serious accident [93mph Anne 'thought blue light was her police escort', 14 March 2001; Geri Halliwell is banned for speeding, 15 March 2001].

 The way to achieve this is simple, but requires a general change of attitude, similar to the one that has occurred in respect to drinking and driving.

 The deterrent should be as simple as it is just: either you keep to the speed limit, or you leave the road. Stiff fines and jail should be reserved for those who drive when they have been banned.
