This^ when I first got the car in December 2021 and it had radar, TACC was decent enough. The acceleration is now much more jerky and slows down too late. Also, in the slightest bit of inclement weather on motorways, it can be close to dangerous when passing as it craps itself and slows down on a regular basis. But hey it works fine in Californian weather so all good
Having had normal cruise for decades and being able to judge/anticipate speed of the cars in front of me, had no issues toggling the cruise speed on the wheel on UK roads without braking. If you can’t do that you shouldn’t be on the road and/or are driving too close up other drivers ar$e’s…
