The laziest cruise I ever used was on my old '83 Cougar.
I set it at 65 and it pretty much did whatever it wanted. I hit [whatever all the way to the right was] several times coasting downhill, and it was so slow it couldn't do more than about 50 uphill anyway.
The car was a 90-hp 3.8L 2-barrel carbed 3-speed auto no overdrive SLUG with airplane gears out back and got 34mpg from PGH to Cleveland and back...
Pulling out up a hill was nearly suicidal, however.
