Cruise control

I use cruise all the time, but each vehicle is different. If your throttle and transmission is doing the same thing you'd do manually, why not let it do it automatically? I can spend less time looking at the speedometer and more time watching the other important things like my mirrors, temp gauges, etc. At highway speeds my vehicle pretty much either runs locked up in 3rd or with the TC unlocked in 3rd. On rare occasions it will drop to 2nd if I push the pedal to the floor but the cruise won't make that happen unless my speed drops quite a bit. Now if my vehicle wanted to kick down a gear more than I'd prefer, I'd probably be more selective about when I use cruise control. As someone else stated, I think under some circumstances I can probably get better fuel economy by trying to use lighter throttle up the hills and keeping the TC locked up.
