Natural selection.. it's only natural!
THIN THE HERD!
If people are too stupid or careless to regularly check things like tire pressure, I can only hope their entire family is in the car with them when it flips over.. we don't need people like that further contaminating the gene pool.
Same goes for those crackheads who don't bother to unload their guns before they clean them.. and right up there with the people who need to be told not to bathe with a toaster.
I don't know about you folks, but when I was a kid, I had to take a drivers ed course. One of the first things they told us in that course was to walk around the car and check things like busted taillights, flat tires, etc BEFORE you got in and drove off.
No "saftey" rule is a substitute for good old fashion common sence.. somthing this country seems to lack more and more every day.
