Perhaps such people just wouldn't read the article because it holds nothing of interest for them, but I'd venture to say a huge fraction of drivers have no idea what ABS really is, how it works, or what benefits it offers. Their only experience with it is "that vibrating feeling in the brake pedal" they'll probably complain to the dealer about after they have a panic stop.

Yes, it's very basic stuff. Yes, any car enthusiast knows about it. No, I don't think it's clear to everyone, even to most people with a driver's license.
