You have to assume something other than a best-case stopping distance because almost all drivers assume they are a "good" driver and will assume they can stop in the minimum distance even when they can't. Most drivers also don't pay enough attention to what's going on to have good reaction times.
- dsfyu404ed 8y agoThere's one right turn I take off a rural road where the telephone poles are 200ft apart. I usually try and see how fast I can stop if nobody is around. I've been doing this for years. The difference between bald Douglas all-seasons one week and the same tires but brand new the following week is the difference between ~400ft@80mph (approximately textbook stopping distance) and about 350ft. I could probably shave off more distance if I had ABS and could plant my foot and make the computer do all the optimization for me. I'm not trying to assume best case. I'm saying we should not assume worst case either. Most sources do the latter because most sources seek to coax everyone into driving conservatively (which is not a bad thing).
