And there was I thinking speeding wasn't a criminal offence. It hasn't, after all, left me with a record (for the one time I was prosecuted for speeding). I would go so far as to say that speeding is something that ALL drivers do at some time, either deliberately of inadvertently, to a greater or lessser degree, and the only way to avoid doing so is to not drive ever.
Just because you think someone is a fool/idiot/buffoon/criminal does not necessarily invalidate everything they have to say.
Many drivers would prefer average speed cameras - ok, so it's because they would probably avoid prosecution if, having spotted one whilst travelling over the limit they could then slow down to avoid exceeding the average, so I'm not so sure they're a panacea. But I do think on roads like the A14, renouned for speeding, they do make a substantial positive contribution. I guess it's horses for courses.
