An Update March 13, 2008
Just today, towards the last quarter of a 300 mile round trip down I-80, I had gotten off in Laramie WY to get gas, started down the road that leads back to the interstate, was doing a constant 45 mph or so, and experienced that unpredictable unintended acceleration - you know, driving along and out of the blue the car starts to take off. Also, I stopped to pee at the rest stop at the Lincoln Monument (highest point on I-80) and on the downhill entrance ramp re-entering the interstate the X3 held a gear all the way to red-line/7K rpms as I entered the interstate. Tell me an automatic transmission in a $46K BMW is designed to red-line. I even drove off the next two exit ramps just to see if I could replicate this upon again re-entering the interstate. Of course, I couldn't and instead the X3 acted much like one would expect, running right up through the gears as I reached 70+ mph and entered back onto I-80.
