Yep, if the car doesn't detect your hand on the steering wheel, the "apply light force..." prompt and the blue flashing border come up and the car doesn't actually change lanes until it detects you holding the wheel again.
EDIT: the flashing blue border also animates in the direction of the lane change, you can see it in this video in a few places:(Video from Firmware 8.5 )
What happened to "automatically change lanes WITHOUT requiring driver input".
@S4WRXTTCS are you seeing what i'm seeing?
