Here is some local coverage of the Utah State University van crash. The accident is getting a bit of national coverage right now, because apparently people are tired of looking at pictures of floods.
1) Nobody was wearing a seatbelt.
2) The van was probably going at least 85. The posted speed limit there is 75, and the van was passing traffic. It could easily have been going 90 or even 95, though.
3) All eleven occupants were thrown from the vehicle during its high-speed, 4x rollover. Nine of them are now dead.
If you drive in the United States, the odds are about 600:1* that you will NOT be involved in a car accident this year. If you drive or ride without your seatbelt, you are playing russian roulette with a 600-chamber revolver and a single bullet. If you wear your seatbelt, you’re still playing russian roulette, but you don’t have to point the gun at your head each time you pull the trigger.
*SOURCE: Extrapolation based on research into the number of fatal car accidents in the U.S., plus my wet finger in the air. There are between 30,000 and 40,000 car accident fatalities per year in the U.S., and more than 10 times that many accidents. If we assume that 250,000,000 Americans drive or ride in automobiles each year, each of them has one chance in about 6000 of dying in an auto accident, and one chance in about 600 of being in an accident at all.
