Slightly off topic...but
From the side view of the controllers, it seems there is only one button (brake), yet the same throttles are marketed in the 2016 range as for the AIR and the PRO. Which leads me the obvious question... where is the lane change button got PRO?
(a) There is only automatic braking for ARC PRO users using the new throttles
(b) There will be a PRO version of the throttle with 2 or more buttons (I'd love to see a button for lights!) (though the web site indicates this is not the case)
(c) There is another way to interact with the single button (double tap? Eugh!)
