Amazing to me how much foolish comment is being expended by officials over something as inconsequential as the possible raising of the national motorway speed limit from 70 to 80mph.

All we’re doing, surely, is bringing ourselves into line with the vast majority of European countries. Much more important, we’re simply adopting the unofficial law Britain’s car-users drafted more than 40 years ago.

Any realist will tell you that for as long as motoways have existed, 80mph has been viewed as the respectable, the stay-out-of-trouble motorway speed by responsible, competent drivers. Go slower, especially in the outside lanes, and you’ll needlessly impede those behind; go much faster and you start catching the traffic ahead.

You can discount all the nonsense about the speed hike causing more accidents or more rapidly expending the earth’s precious resources. I predict surprisingly few of us will drive any faster or slower. The “fatality” and “CO2” arguments are being formulated, predictably enough, by that curious band of commentators who mysteriously claim to know what’s right for cars while glorying in having as little as possible to do with them.
