New X has I think 2,500 miles on it by now. Long trip yesterday - About 8 highway auto-steer hours - lots of long straight stretches on nice roads. Car was constantly hunting (oscillating) for a perfectly-centered track and making ultra slight adjustments left to right to left - enough that you'd think it was gently rocking you to sleep. IS THIS NORMAL? Frankly, it drives better than I do even with this, judging by the number of times my driving engages the lane departure vibration (super sensitive, in my opinion versus former BMW). I have the smaller tires so it doesn't feel quite as "on rails" as low profile tires on my S provide, but understandable...It's an X with mushier tires...(yes, perfectly inflated to specs) Just DANG! the slow rocking side to side... SC offers standard response about my AP questions - improvements coming. I invite pleasant responses and thoughts and ask that the smarty-butts "steer clear."
