Yes, but there are also adaptive cruise controls with manual gearbox, and it's a useful combination in highway traffic. Or even in suburban roads: I don't have it, but I use regular cruise control quite a lot on roads that have traffic lights every 1-2 km, and the speed of traffic varies between 40-70 km/h.
