Before I retired, I used to drive around 45,000 miles p.a, with probably 40-50% on Motorways where cruise is definitely a boon, and I have used it for many years .
I now have ACC on the Tiguan, and it is a different beast from normal Cruise Control, but really comes into it’s own on the motorway, however, it does take time to adjust , and to adapt to it, but it is really worth persevering with it!
It is a brilliant safety feature, rather than a convenience!
I use it on local roads and in traffic also, and I wish that it had been available to me when I was working!
