Break HOLD is not the same as the Creep / Roll / Hold option being asked about in the OP. Your '16 does not have the feature being asked about.
No kidding. Re-read the quote to which part of his statement that I am referencing. How else do I paint this for you in order to comprehend?
Two separate things are being addressed. A handful are talking about the different features offered up by the Model 3 that the OP mentioned; creep, roll, hold.
Myself and a couple others are talking about the OP’s part of his statement that if he lets go of the brake pedal the car moves. Our posts are in regard to this, and only this. Our cars will hold (H) after releasing the brake. We know it’s not the same as the Model 3.
