I was amazed to listen to some people recently on JoAnne Good's radio programme griping at being caught doing 36mph in a 30mph area.

I suppose they are quite happy to do 84mph on the motorway although the limit is 70mph?

In both cases, the extra is 20 per cent above the limit. What do these people think the limits are there for anyway?

They are lucky they are not in some parts of Wales, where the police are much less lenient - you can be stopped for doing 32mph there and receive a warning.

It's no good saying your brakes are good; if you are less than two seconds away from the car in front and it pulls up sharp, you have an immediate shunt.

The term will be "Failing to maintain a safe braking distance".

So, slow down, stick to the limit and be smug when the car in front that has just gone past you gets nicked.
