Good point! Definitely be useful in stop/go traffic....lolI used to laugh at the off-road cruise control, but lately I have been using it more and more in two scenarios.
First is in traffic that is not stopped. Set the speed and no need to go from gas and break non-stop.
Second is during hunting. During small game hunting season, I set the speed to 10km/h, 6mph, and can focus on looking around for small game while I'm going to a spot or bringing stuff for big game hunting.
Ford makes their Trail Control available in 2H to 4L which definitely increases it's use. Sadly, Toyota's Crawl Control and Jeep's Selec-Speed is only available in 4L, like so many of their other 4wd features.
