Hill-start will just hold the brakes for a short time, maybe a second or so, so you don’t roll backwards when starting on a hill. Can’t think of any negative impact…
I have it turned on with both my manual fords, I like it. Remember the anxiety of learning to drive MT and getting stopped on a hill! My kids are spoiled with this technology! ;)
I swear that I had the hand throttle on my 72 Bronco, used it as kind of “trail control” , but that was a long time ago!
