On my previous Galaxy (2.8i auto 1997), the cruise control nearly caused me to have an accident the first time I used it. I had it set at about 70 on the motorway and the traffic slowed down so as I braked the cruise control cut out as expected, one the hazard had cleared at about 35mph, I re-engaged cruise control and the cruise control dropped the accelerator to the floor, the auto kicked right down, revs up to near the red line and nearly ended up the back of the car in front.
