In the past, I've slammed on my brakes from 100km/h with engine off to test my brakes out and I recall bald spotting a tire in the process... more my fault, but it brings up the thought

Does your ABS system still work with engine off?

What about other secondary systems, vehicle stability control? does anything change with function of other safety devices for your vehicle?

Plus a few more...

Since the biggest benefits to drafting a truck are say within 10 ft of his rear bumper, is it really worth it?

There are definitely some tactics that I have a personal problem with, as I don't believe they are safe based on how newer cars function.... BUT I also have a big problem with labelling the rest of the well thought out and extremely effective and safe hypermiling tips as unsafe.
