We were coming home on the interstate in our 1 month old Inscription tonight and noticed something really cool! I had the the cruise set at 73mph and the car kept us between the lines without any assistance from me. I had originally thought that the lane assist feature wouldn't work over 30mph but I guess it does! I had heard on this forum that the S90 would do this up to 80mph and thought it would be nice if the XC90 could do this...well apparently it does!!
