OK. That makes sense … if you are on a hill. It still doesn’t explain why someone needs this on at a stop sign or traffic light.
On my Teslas, I just kept “creep mode” on which accomplished what you are describing without having to lock the brake system. It programmed the car to behave like an ICE car that was using engine torque to move forward if you let off the brake. I was always surprised when folks said they turned that off.
That being said, your earlier post said that the GT had the always on … that its transmission always had some type of “pull” in place.
So the question remains, if the GT doesn’t keep a completely neutral stance, and always behaves like an ICE manual transmission … then why does someone need this feature activated. You certainly don’t need it for stop signs/traffic lights and if the transmission on the GT always has some ”pull” then even when parallel parkin on a hill, you should be fine.
BTW: for some reason, I keep thinking about Bill Colby’s old schtik about driving in San Francisco in his Volkswagon Bug and having someone put a fake stop sign at the top of the hill, then watching with binoculars and saying “look Martha we got another one”. And his whole punchline of dying while drifting backwards into the Bay in his VW Bug because he couldn’t shift fast enough to get started from the stop sign.
Oh well. Yeah, I’m old.
