I can't remember if I've posted it before but I know of others with this issue. A much earlier technology, emergency brake assist, caused an accident in what was the first car that had it (IIRC). I braked hard in an emergency fashion but then realised I had much more time and space, the car disagreed and kept full pressure and the car behind went into my backside. The driver thought I wouldn't keep my brakes on, which I didn't! So they didn't brake as hard and it caused an accident.
Can I suggest something? It sounds dumb but give it a chance: Flip a coin, heads you buy an RS, tail
