I have never heard this method of calculation used by any official entity--- mostly just people repeated "what they've heard". It just seems like a vague and ill-defined rule. What, exactly, is a "car length"? Well, we know a Vanagon is 14-15 feet, but who can really calculate, by eye, on the fly, from the driver's seat, 6.5 Vanagon lengths at 65mph? And is that really enough? The "rule" I've seen from most government safety busybody agencies is "2 seconds in good weather". Two seconds following distance is 190 feet at 65mph... which is a dozen "Vanagon lengths". -- John Bange '90 Vanagon - "Lastwagen" '90 Vanagon GL - "Wiesel" |
