I use it pretty much all the time. from country roads to motorways. when my car has locked on to the car in front I feel it is using the throttle to regulate, and only the brakes if letting off the throttle is not enough to maintain the distance.
in slow traffic I guess the brakes are used a lot more, so I guess you are right about your assumption.
I asked BMW this question because before I had ACC, when I was coasting, or braking using a gear down an incline, I would tap the brake, or just put my foot on the brake to get the brake lights on without actually braking to inform others that I was slowing down.
