We now have 10 years of evidence proving that the only "assault" was on the sanctity of the truth. The nearby table shows that the death, injury and crash rates have fallen sharply since 1995. Per mile traveled, there were about 5,000 fewer deaths and almost one million fewer injuries in 2005 than in the mid-1990s. This is all the more remarkable given that a dozen years ago Americans lacked today's distraction of driving while also talking on their cell phones.
Of the 31 states that have raised their speed limits to more than 70 mph, 29 saw a decline in the death and injury rate and only two--the Dakotas--have seen fatalities increase. Two studies, by the National Motorists Association and by the Cato Institute, have compared crash data in states that raised their speed limits with those that didn't and found no increase in deaths in the higher speed states. . . .
We are often told, by nanny-state advocates, that such public goods as safety require a loss of liberty. In the case of speed limits and traffic deaths, that just isn't so.
