I took delivery of my MX this week and while going over the car I was told about a new sensor that is now built in to the interior of the Falcon Wing doors. The sensor checks if anyone is present underneath the door prior to closing. I have tested and can confirm that it works. Before I received my MX two people did get tapped with the door so I love this new feature. How does it work you ask... When you press the button and are still standing under the door, the door will not close. Once you move it will then shut. Now, what if you do not move? In this case after about 5 seconds you will hear some quick beeping and the door will time out and remain open until you press again.
