This one time, I was at a bank getting hooked up with a savings account. The friendly bankerperson doing the paperwork with me said "Wow. I've never seen anyone actually read the form before signing it."
You would think that the idea of handing hundreds or thousands of dollars to total strangers who promise to take good care of it would motivate people to cast their eyeballs over some turgid prose, but it doesn't. I don't think there's anything that can motivate anyone to read anything *especially* warnings that most of the time don't result in the machine halting and catching fire.
