The Most Dangerous Machine

Thursday, December 5th, 2013

The most dangerous machine in modern America is the automobile:

  • More than 33,000 Americans die per year in automobile accidents.
  • This is despite the fact that the rate of fatal crashes per automobile mile driven has declined by two-thirds since 1975.
  • One of the earliest safety innovations was putting a line down the middle of the road. Having a centerline on a road will cut crash frequency by at least 20 percent.
  • Until the 1980s, seat belt use was only 10 or 15 percent; today, we’re up to about 86 percent. Seat belts reduce the risk of death by as much as 70 percent — at a price of $25 a piece. There’s one life saved in the U.S. for every $30,000 worth of seat belts installed in cars — versus one per $1.8 million for air bags.
  • Over the last ten years, alcohol-related traffic fatalities have fallen by 28 percent.
  • Younger drivers tend to be more dangerous. In 1980, 18 to 29-year-olds were 30 percent of the population. By 2000, that number was down to 22 percent.
  • Driving in a city might seem dangerous, but wide-open stretches of rural road are three times more dangerous.
  • Cell phones are a dangerous distraction, but they also save lives, by getting emergency personnel to the crash site much sooner.

  1. Driving in a city might seem dangerous, but wide-open stretches of rural road are three times more dangerous.

    Presumably on a per mile, not per minute, basis. Makes perfect sense, tho’ one wonders whether they count car-jacking.

    What I’m really curious is this: What fraction of auto fatalities involve one or more parties who can not legally operate their vehicle — whether for no license, suspended license, no insurance, etc?

    Putting a line down the middle of the road requires you to have a road wide enough for one. Where I live most roads are too small for lines. The widening of a road to allow for a line would lower the accident rate in itself.

    Then again most accidents here are single-vehicle accidents involving trees or ditches [and likely Armagnac, Madiran and/or Côtes de Gascogne]. Not sure a line is going to help with that.

    Maybe if they drew lines around the trees?
