My Ateca has it, and I hate it!!
It’s fine for motorways but around town/B roads etc. mine is a pain!, if someone in front turns left it slams the brakes on, even though I’m not even close. I don’t mean it slows down, it literally almost brings me to a full stop while still in 4th or 5th gear causing the engine to stall. Approaching a roundabout with the car in front slowing or passing the odd car parked at the side of the road often triggers it to do the same.
I’d prefer standard cruise control but you can’t have it, it’s either ACC or speed limiter which is about as useful as a chocolate fireguard 🙂
Please excuse spelling/typos. Apart from being a clot it turns out I had one on my cerebellum that's now causing various problems!
