Having played with it, I would have liked it, but it's not a huge deal breaker. I'd imagine though, that a well-designed ev-specific ACC would get really good range by keeping the car at an efficient speed and using regen when needing to slow down.

This was the deal-breaker for me. Lack of adaptive cruise control is the sole reason that I'm not buying a Model S.
I still think that anyone who puts a car into cruise control in the middle of traffic is endangering not only their lives but the lives of others on the road. But clearly my view is not commonly held.

Adaptive Cruise Control has been around for over a decade, but one issue with the system is that it just keeps track of the vehicle ahead. Nissan's Predictive Warning system takes the concept to the next level.
Using the same radar-based sensor mounted in the front bumper, the system detects the second vehicle ahead by extending the radar's range underneath the vehicle directly in front. If that vehicle doesn't brake in time the system alerts the driver with an audible warning, and when the driver directly ahead swerves out of the way, both an audible and visual warning alerts the driver of an impending collision and pretensions the seat belts. While Predictive Forward Collision doesn't brake for the driver, linking the ABS wouldn't be difficult, as you can see in the second demonstration in the video above. And before you ask, the system can still detect the second vehicle in line, even if the Civic directly in front suffers from a terminally low stance.
Also, they have an established relationship with Mercedes already.Wido, I'm sure that Tesla could license the tech from Bosch, and probably buy the whole package from Mercedes. The latter seems the most straightforward, so that all of the extensive learning and testing that has gone into Mercedes' proven product doesn't need to be replicated by Tesla.
I can see that use; it's when people talk about using it in LA traffic that I get queasy.While I'm sure people do it, ACC is not designed primarily for stop and go traffic. It's meant for cruising. It's very useful, for example, when I'm cruising back from NYC and there's a truck or something that merges temporarily into my lane. Rather than hitting the brakes and disabling cruise control the car automatically slows down and keeps me a safe distance back. As soon as that car moves from my lane the car accelerates back to previous cruising speed.
When I test drove this vehicle, the salesperson wouldn't let me test the ACC, because he was afraid he would lose his job if it didn't work and I crashed the car!
When we got it on the car we have, the salesperson on the test drive told me to leave it on as I approached a light and "watch it magically take over for you". It didn't. I ended up hitting the brakes before he even realized that the car wouldn't. It's a great tool, but far from an autonomous experience.
BMW's non-ACC cruise control does a great job with this. When you set the CC speed, a hand sweeps to a position on the speedometer and stays there even if you suspend the CC.Many cars don't resume accurately so you have to fiddle with it every time. And it's much easier to set to the speed you want because it's got a target speed readout.
I find that latter feature just as helpful as the adaptive part. Probably wouldn't require a lot of engineering to have an accurate target speed display on a conventional cruise control...

I agree, ACC is the one "luxury" feature that I will really miss in the Model S. Given the powerful and quiet drive train, it could be difficult to keep the car in the desired speed band without constantly looking at the speedometer.
Is this correct?2014 will be the "precrash safety system" required in the EU , which is basicly a fullstop ACC ...
... So by End of 2013 Tesla should be Ready ...
