I have mine set on 7 all the time. It still sees slow moving traffic very late for my liking and then brakes hard. It's fine when following fast moving traffic which then slows down. The problem is when you are approaching a line of slow traffic at high speed, it simply can't see far enough ahead to react sensibly and bleed off some speed on initial approach. So I just switch out of AP in that situation and brake manually.
The other thing I don't like is when a car pulls out in front of you at high speed, AP tends to over-react and brake much harder than I would manually. It doesn't make the same flexible use of the gap to the car in front when braking as you would when driving manually. So that's another potential for getting rear ended I guess.
But overall I don't feel more or less vulnerable to being rear ended in the X than any other car. I think where you are driving is a much bigger factor and luckily in the UK it's not a major problem.
Agreed.
What I do when seeing traffic slow and/or stopped in front of me (whether from a stop light or traffic related) is to quickly ratchet down speed (sometimes as low as 18mph setting) so that X will approach the stopped cars much more slowly and it will ease to a stop.
Having setting at 7 gives me the time to do that and provides room to go forward a bit if some other driver behind me is not paying attention.
