Prevent others to get in when you are inside the car

[sakimano]

yes. That works. I tested it out today too.

Never know that there is a lock icon on the screen. I tried the Lock icon in my iPhone and that didn't work.

Haha, forum is great.

Manual is even better

Actually, I also tested clicking the lock icon on the screen while the car was in park and then pushing the exterior door handle . The door remained locked and did not open. Easy enough for any Model 3 owner to test for themselves.

I tested this on Saturday and got the same result. The car cannot be entered from outside when the lock icon on the screen has been pressed, even if the driver's phone is in close proximity.

Asking for a friend... you've got time to kill so decide to "netflix and chill with your gf", you don't want someone walking up to the door and just be able to open it. I know this doesn't work while in Drive, but neither does Netflix and it goes into Park after a few minutes of sitting in Drive. So this is a genuine scenario.
