After driving to central Italy, in one go, between 2 drivers, but no cruise control, never again.
As others said, it's all about planning, reading the traffic.
Drove a golf which had the adaptive cruise control, and the (remote I must say) chance of the system suddenly brake the car because of a false reading, which happened just once, put me off. But 99,99% of the time was a pleasant experience.
Friend of mine has a Seat with the same system. 3 times in the last week it's performed an emergency stop with nothing in front.
Dealership is denying there's an issue.
