michigan state police say most speed limits are too low
Michigan State Police photoIn his capacity as the former head of the MSP’s Traffic Services Section it was Lt. Gary Megge’s job to eliminate speed traps set up by local municipalities. A few years ago Megge told the Detroit News, “I’ve spent eight years in traffic services, and I was a crash reconstructionist for five years before that, so I’ve seen my share of fatal wrecks, and I can tell you: Deaths are not caused by speeding. They’re caused by drinking, drugs and inattentiveness. The old adage that speed kills just isn’t realistic. The safest speed is the speed that is correct for that roadway at a given time. A lot of speed limits are set artificially low.”The state police were one of the groups who backed, against the lobbying of municipalities, a change in Michigan law that required speed limits to be set based on actual traffic data and engineering studies. That law, Public Act 85 proposed to set limits based on what is known as the 85th percentile rule, a widely used measure that sets speed limits at how fast 85% of drivers travel safely. “It just doesn’t seem right to me that we would enforce a law where 90-98 percent of the people are in violation of it,” Lieutenant Megge told the DetNews in 2008. “It’s not the way we should do business in this country.”After that law was passed, cities, towns and villages, through the Michigan Municipal League, pointed out that the law didn’t specifically require traffic studies and lobbied against revisions to Public Act 85 that would force them to due such studies. At the time, Megge agreed with them, to a point. “There is nothing in the code that specifically requires a municipality to conduct traffic studies,” said Megge, “but enforcement of any law must match the criteria of the law,” technically making invalid those tickets issued on roads whose speed limits were not compliant with P.A. 85. The cities opposed using such studies because they almost invariably call for higher speed limits, potentially reducing revenue from speeding tickets. The revisions eventually passed in 2010.Since then, Lt. Megge’s job has been overseeing such compliance. Over his career he’s had a hand in the raising of over 400 speed limits across Michigan (though in a small number of cases the studies resulted in lower speed limits). By now there’s more than a decade’s worth of data from those raised speed limits and Megge insists that higher speed limits don’t mean that people drive significantly faster. They drive just as fast as they always did before, and just as safely. They just do so without risking points on their drivers’ licenses. The lieutenant says, “Over the years, I’ve done many follow up studies after we raise or lower a speed limit. Almost every time, the 85th percentile speed doesn’t change, or if it does, it’s by about 2 or 3 mph.”In addition to the fact that they don’t really do anything to promote traffic safety, Lt. Megge says that unreasonably low speed limits actually make roads less safe by diverting resources away from the kind of law enforcement that has measurable effect. Megge recommends, instead of zealous speed enforcement against drivers who are effectively safe, focusing on drunk drivers, red light runners, drivers and passengers who don’t buckle up, and, an important point, enforcing realistic speed limits against the small minority of drivers who unreasonably and excessively speed.Alex Mayyasi, at pricenomics.com, has an extensive look at how speeds limits have been and are being set, including an interview with Lt. Megge.

    Started driving in the '70s and have garnered exactly one speeding ticket. If nefarious revenue conspiracy this be, hasn't much worked with me. Non-issue.

    Increased speed limits on freeways would be nice, but I'd be afraid of merging. Not because I can't get up to the required speed within the confines of a typical Minnesota entrance ramp, but because I always get stuck behind the people who don't understand that getting to freeway speed is the who point of an acceleration lane - and usually hit the freeway at 40 mph. There's nothing more exciting, in an explosive diarrhea kind of way, than getting onto a 70 mph freeway going 40 mph merging in front of a 70 mph semi with nowhere to go. There have been times that I have hoped for a red light getting onto the freeway (as long as I'm first in line) so that I could get to speed and safely merge. When I have my druthers I usually hit any freeway at 75 mph.

      See my post above!! Right down to having my day -- no matter how bad things may have gone at work -- being made a little brighter by being the first person out of the blocks. (Well..as long as nobody pulls into the lane prior to the break-off. Haven't had to ABS behind one of these fools yet, but it's a buzz-kill for sure!) It's one reason of many that I WILL have a V6 (or above) on the other end of my (lead) right-foot as long as I am able!

  • Gemcitytm Why does it seem every EV seems to have ridiculous amounts of power? Yes, I know they're heavier than ICE models but who on earth needs 708 HP? How about a nice, compact EV with, say, 250 HP and 350-400 mile range? Is that impossible with today's tech? (I currently drive a 148 HP Mazda 3 ICE and it has all the get-up-and-go I need.)
  • CEastwood I could have bought one of these if I had the cash in 76 for $1000 white , red interior , 3 speed stick with whitewalls/ wire hubcaps - it was mint and gone a day after I saw it . But the real catch that got away was an all original 69 green Camaro RS convertible 327 4 speed with 46K on the clock for 1800 that I saw a few months earlier . Young and poor was not a fun place to be !
  • KOKing I'm in an emissions check only state, and I'd trade that away for a safety check all day.
  • Bd2 The hybrid powertrain in the Sportage and Tucson are the ones to get.H/K should discontinue the base NA 2.5L powertrain and just build more of the hybrid.In the future, maybe offer a 2nd, more powerful hybrid (the hybrid 2.5) which will first arrive with the next Telluride/Palisade.Kia also needs to redo the front fascia for the Sportage's refresh.
  • The Oracle I say let the clunkers stay on the roads.
