“As long as most people speed, obeying the law can be dangerous” By Frank Williams on July 21, 2008 That's what The Star-Ledger columnist Bob Braun (via nj.com) concluded when he drove the same 55-mile route two times: once keeping pace with traffic, and once at just above the 65-mph speed limit. If you've driven on the highway anywhere lately, I don't need to tell you the outcome (but I will anyway). Keeping pace with traffic, Braun drove 80 – 85 mph and had no cause for concern. Driving 68 mph, he was passed by almost everyone, tailgated and found himself in dangerous situations more than once. He quotes Charles Lave, University of California at Irvine economist: "I find that there is no statistically discernible relationship between the fatality rate and average speed, though there is a strong relationship to speed variance. Variance kills, not speed." Perhaps the lawmakers need to be reminded of this fact as they consider lowering speed limits in the name of saving fuel. (An aside: does that mean the more fuel-efficient a car is, the faster it'll be allowed to go?) If our elected representatives are stupid enough to drop the national speed limit back to the double nickel, accident rates will go up as the variance between those who want to get there in a reasonable time and those who drive the speed limit increases. It makes more sense to raise the speed limit for safety's sake. As Braun points out, "if everyone uniformly sped, or, if everyone obeyed the limits, then we'd be safer." And you know the majority aren't going to obey the limits.
