2009 Pontiac and a 2013 Fiat, so relatively modern.
Couple of possibilities then, I suppose:
* They do work towards a set speed, but I'm too impatient and reset the cruise control before they achieve it.
* Cruise control operates differently on cars with manual transmissions. I've never actually observed cruise control behavior in an automatic because it's been broken on the automatics I've previously owned.
- rkangel 9y agoI have a 2001 Porsche Boxster (manual transmission). It will maintain speed as long as their is sufficient torque to do so in the current gear (or engine braking depending on uphill or down hill). Is it possible that you don't have much excess engine power at highway cruising speed and the car is only slowly responding to change in incline?
- lfowles 9y agoQuite possible! I'm currently in Kansas or I'd be out finding some hills right now to test this further.
