PS: Please don't gave a great debate about it being "dangerous" or whatever, Iv seen people travel behind semi's at like 15 feet, they are pretty crazy...
PSS: How old is everyone here? Just wondering, Im 19, turning 20 on July 25th

I ran some rough numbers for my car, a Land Rover LR3 HSE (what else would a hypermiler drive?) and wrote a blog post
here. Driving 55 m.p.h. unaided and 59 m.p.h. drafting at about 50 feet should produce about the same fuel economy. Drafting at anything faster would decrease fuel economy from 55 m.p.h. unaided. Needless to say, not too many trucks are going slowly enough to make it worth it for me.
I'm not willing to get closer than 50 feet due to some calculations I made that are detailed
here.
