Sometimes simple designs are good. Older cruise control designs are quite primitive but very effective. Nothing but a simple feedback loop. Car not fast enough? More gas. Too fast? Less gas. The smarter ones (probably ones with electronic transmissions) would even downshift to keep under the preset speed. I bet the earliest ones were all mechanical too. Of all the features in a vehicle, I don’t think you need to worry about “standard” cruise control.
