I've had my M3 AWD for about six weeks. Today was my second day driving it while snowing. The first was actually when I picked it up! So, today was the first time for snow driving after I've gotten used to the car.
During the initial freeway drive I had TACC engaged and was monitoring it. It's a good thing I was, since it was happily closing on the car in front of us with no indication it was going to slow down. I applied the brakes myself. It wasn't too long after that I got a warning that TACC was now available due to visibility conditions.
That leads me to a question: why is there no fallback standard cruise control? I'm pretty sure the versions w/o EAP hardware have a standard cruise control and it seems likely that the EAP hardware has the necessary speed monitoring and control of accelerator to implement standard cruise. I imagine T thinks the drive would be confused about cruise control mode and not be monitoring the traffic situation for speed changes. Still, I wish there was fallback cruise control, even if I had the proactively engage it.
BTW I -love- my car, this wasn't a complaint, just an observation agreeing with T's warning that the driver must be monitoring the road conditions and that AP features have limitations.
