Why we ignore thousands of daily car crashes
I was a cop for several years.  I worked hundreds of crashes, and a few fatalities.<p>If cars had a max speed limit of 85 mph, and required the seatbelt to be engaged to work, we&#x27;d cut our fatality rate in half.<p>Most nations&#x27; DUI laws consider a 0.05 BAC as illegal. In most US states 0.08 is presumed under the influence, 0.06 - 0.079 is considered no presumption either way, and under .06 is considered not under the influence. My alcohol tolerance is fairly average, but after some off the cuff experiments with whiskey and a preliminary breathalyzer, I shouldn&#x27;t drive at a .055.  My wife shouldn&#x27;t drive at a .03<p>Something like 80% of fatal crashes involve either alcohol, no seatbelt, or excessive speed, but not wearing a seatbelt is like a 50 dollar ticket, and a secondary offense, in many jurisdictions.
