Will be buying a 450h in the nearish future (hope to pick up one that's been traded it when the new GS is launched).
One thing on my must have list is the ACC system. I'm a great fan of cruise control, and use it most of the time, especially in 30s, 40s and 50s to make sure I don't speed.
My question is how 'intelligent' is the ACC? for example:-
If you're on the motorway, does the radar ever think a car you're overtaking is actually in front of you and applies the brakes or slows down?
If you're following traffic on a normal road, does the radar ever 'lose' the car your following as you go through bends, causing the car to accelerate to the pre-set speed as it thinks the car has disappeared, only to suddenly brake when it 'sees' the car again on the next straight?
Also, I've heard that the ACC only operates at speeds of 30mph or above is this true? If that's the case, what happens if you approach a 30 zone and reduce the set speed to 30 and then come up behind something going slower. Does that car slow itself, or do you have to brake or press cancel (like a standard cruise control system)?
Hope someone out there is also a cruise fan and can answer my question.
Cheers, Ian.
