Motorways are, no doubt, the safest roads in the country. Mile for mile, vehicle for vehicle, you are much less likely or seriously injured than on an ordinary road. On the other hand, if you do have a serious accident on motorway, fatalities are much more likely to occur than in a comparable accident elsewhere on the roads.
　　Motorways have no sharp bends, no roundabouts or traffic lights and thus speeds are much greater than on other roads. Though the 70m. p. h. limit is still in force, it is often treated with the contempt that most drivers have for the 30 m. p. h. limit applying in built-up areas in Britain. Added to this is the fact that motorway drivers seem to like traveling with perhaps barely ten meters between each vehicle. The resulting horrific pileups(involving maybe a hundred vehicles) when one vehicle stops for some reason—mechanical failure, driver error and so on—have become all too familiar through pictures in newspapers or on television. How many of these drivers realize that it takes a car about one hundred meters to brake to a stop from 70 m. p. h. ? Drivers also seem to think that motorway driving frees them from sudden change of the weather. However wet the road, whatever the visibility in mist or fog, they plough at very high speeds oblivious (无视) of police warnings or speed restrictions until their journey comes to a premature conclusion.
　　Perhaps one remedy for this motorway madness would be better driver education. At present, learner drivers are barred from motorways and are thus, as far as this kind of driving is concerned, thrown in at the deep end. However, much more efficient policing is required, for it is the duty of the police not only to enforce the law but also to protect the general public from its own folly.
