Does any manufacturer have an Adaptive Cruise Control that can completely stop the vehicle ? I don't understand why this is so hard to do ?

Maybe I'm missing the point here... but if the car in front of me slams on the brakes, I'm going to be slamming on the brakes as well... I wouldn't trust that the car would understand the severity of the situation -- plus it's just reflex.
I asked him if the Model S would offer it and he said that "it hasn't even been brought up or discussed".
In 2006, Toyota introduced its "all-speed tracking function" for the Lexus LS 460. This system maintains continuous control from speeds of 0 km/h to 100km/h and is designed to work under repeated starting and stopping situations such as highway traffic congestion.
The LX has become a technology showcase for Lexus.It is the first Lexus to offer a wide-view front and side monitor system for hard-to-see areas, and incorporates the new Adaptive Radar Cruise Control and Pre-Collision System.....Cameras are located inside the grille and side view mirrors, and the radar antenna is located behind the Lexus emblem in the front grille. ...
Even at this distance, there is still a noticeable impact on mileage when following a truck. It turns out that at 70 mph using the adaptive cruise control is good for about 1.5-2 mpg improvement in efficiency compared to running in clear air. Moving in tight really only picks about another 0.5 mpg. At the same time if the vehicle you are following slows, your vehicle will also slow to maintain the distance. In the case of the Q7's ACC it will bring the vehicle down to a complete stop, unlike many such systems that deactivate at 15-20 mph.
According to Audi engineer Gunter Schiele, the Q7 ACC has been calibrated specifically to maximize both comfort and fuel efficiency. Often traditional cruise control systems try to maintain the set vehicle speed aggressively which leads to the transmission down shifting and hard acceleration. With the focus on comfort, the Audi's acceleration is kept moderate. The result is smooth behavior that also allows for decent fuel efficiency.
he Roadster is lacking). It's a tough call, but I'm 90% sure that I'm going to cancel. If I *do* end up cancelling, 99% of the reason for my cancellation will be because of the lack of adaptive cruise control.
That's likely to raise some eyebrows @ TM HQ
...Also new to Toyota is an available Dynamic Radar Cruise Control system that uses advanced millimeter wave radar. The system also enables Lane Keep Assist, which helps the driver stay safely within the lane, and the Pre-Collision System, which retracts seatbelts and applies the brakes in certain conditions when a crash is unavoidable...
