That is it.
With all this stuff you can of course turn it off but it is every time you start the car.
You do have to have your wits about you for what I call spurious speed reductions. Eg driving at 70 and suddenly it reduces to 50 for no obvious reason.
One thing that I do think is clever is in Spain we have a lower limit on motorways for bad weather eg rain. The two limits show on your dash with the correct one more prominent. If it rains and you use your wipers, then it reverses and puts the lower limit prominent.
All sort of clever stuff but sucks the joy out of motoring as johnnydog and Andy say.
