Yeah... The radar cruise control is awesome. I have even used the stop/start function of it in peak hour and it works like a charm. Brings the car to a complete stop and a quick tap on the accelerator gets the car moving again.
I have noticed the heavy breaking when a car turns off the road in front of you. It really does break hard and I will usually disable it when I see someone turning off because it will bleed 30-40km/h off my speed.
The AEB has activated once when someone cut in front of me. Now that was an experience, the car lit up like Christmas and a fog horn went off!
