On our Tiguan the intelligent cruise control won’t let you undertake which can be frustrating and embarrassing in some circumstances.
We do a lot of motorway miles and it’s mind blowing some of the lane hogging I’ve seen and general bad driving I’ve seen, but tooting then and flashing them will lead to even more road rage and bad driving.
As the item says some drivers won’t move over into lane one until they are leaving the motorway.
The M25 is a classic example as you find even on the four and five lane stretches lane one is empty and the others are jammed with lane hoggers so the traffic still builds up at peak times.
