They have, and for a while they've been optional. Unless I'm mistaken, they're standard nowadays. And this isn't just from Ford, GM, and Chrysler. The imports add them too, in fact I really don't know of any car manufacturer that doesn't at least offer cruise control. If you've read my profile, you'd realize my car is a 12-year-old Honda Accord, and that has it. My 1991 Toyota Corolla had it, but my '97 Corolla didn't.
