Any Model X owners with 2018.2 tested the rumored feature that the FWD does not close when someone is standing underneath? See reddit post for background -
2018.2 Model X • r/teslamotors
Small note from that thread:
Inward facing ultrasonics were implemented sometime around November of 2017. Therefore not all MX have this ability after the update. The sensors are located behind the speaker grill in the falcon doors.
So only newer Model Xs have this feature...
