It can be a bit of a nuisance, especially when the roads are busy.
Personally I don’t like it as I feel it slows you to early, even on the closest setting.
Plus if you pull out to overtake and you’re a bit close to the car in the lane you just joined, it will hit the brakes. This can cause further annoyance to car behind that you just cut up and trigger even more gestures and blood boiling. Fortunately, the Jag has good sound deadening and ICE so I can bearly hear the horn that’s blasting at my rear bumper and as I never look in my mirror, I have no idea what gestures are being aimed at me.
However, with follow mode turned off, I can bumper biff the car in front as well. This causes a great light display of flashing red in front of me and bright white behind. It’s like being at a jean michel jarre concert.
