On the same day Gov. Jennifer Granholm suggested the state consider lowering freeway speeds to conserve gas, speed studies released to The Detroit News on Wednesday indicate that $4-a-gallon gas has not put a damper on the desire to zoom across town.
The average speeds at nine spots around Metro Detroit actually rose from August 2007 to June, according to the Michigan Department of Transportation. Speeds went down slightly at just three sites that MDOT routinely monitors.
It is classic time-is-money tradeoff, said David Greene, a researcher for the U.S. Department of Energy based in Tennessee. A motorist can save $12 in gas by going 10 mph slower over 500 miles. But it adds an hour to the trip.
“For a lot of people, their time is still more valuable than the fuel savings,” Greene said.
Police and others say slowing down too much can be dangerous. Some folks are tempting fate by dipping below 55 mph, said Jim Rink, a spokesperson for AAA Michigan. If most traffic is going 70 to 75 mph, the slow car becomes a danger, he said. “It’s a recipe for a potential crash,” he said.
For that matter, why are taxes being imposed for any purpose other than supporting government functions, and why is there such an obsession with taxing anything you don’t like?
If the government can give out incentives for hybrids, why not incentives for any car that exceeds 30 mpg combined? What about supporting a SUV buyback program if people are so hellbent on getting these things off the streets?
What is so attractive about beating people over the heads with excess taxes and excess regulations?
If the motivation is to save fuel, then instead of slowing people down, the goal should be the opposite — to get traffic to stop idling. Unless you drive a hybrid, your worst fuel economy is achieved in slow stop-and-go traffic, not at highway speeds.
