I had hill assist on my last truck and to be fair it was great. Bare in mind if fully freighted I was run in at 44 tonnes, it never let me down. Never had it on a car tho.That's something I need to try. Never had the guts to trust the electronics to do that hill-start malarkey. I suppose 35+ years of driving it's hard to hand over to some software engineer. Having been one for many years I have a healthy disrespect of things designed by me.
If the wheels are locked by the brake, how do they turn?
