Your math is a bit off...your math includes one object moving and the other stationary. If you're both doing 35 miles an hour then you're following distance is closer to 2 car lengths. If you're doing 60 it doubles to about 4-5 lengths. Unless you're joking, you've obviously never done the count to check. Not knocking ya...just sayin. I actually really like the 10 point commentary and the 5 seeing habits. They're a really good tool for driving big trucks and my own vehicle. I'll teach my kids to drive with the same methods...only without the memorization.
