Dear Owner (by the way, IMO, not the most practical username for this forum. Only one step up from Generic.)
I agree with strider and imherkimer it might have been left unlocked accidently.
A couple of years ago, there was a thread here of an owner that kept finding his lift gate open when he was parked at home. Not at work, but at home. 1,000 suggestions as to why. He finally figured out it was his new leather fob cover. The snap was pushing the trunk part of the fob when he sat down with it in this jeans pocket - in the house. He played detective and figured out, he parked far enough away at work from his desk, that when he would have triggered the fob, he was too far for the signal, and he never wore jeans to work.
And rdrcmatt might have nailed it. The fob might have been inside the car.
You mentioned in post #7 that you need to take the fob out of your pocket before the door handles retract. If you are carrying your smartphone in the same pocket as your fob, the smartphone is interferring with the fob's signal. When you separate the two, the fob's signal is getting to the car.
And you mention if the car was unlocked, the door handles would have presented itself upon touch. That's true nearly all the time, but not 100% of the time. So, that car could have been left unlocked.
In case someone didn't know, the fob holder and double click and unlock the car and the handles present. But don't open a door or the lift gate, just walk away. In a minute the handles will retract, but the car is left unlocked until someone approaches and touches a handle to present and pulls the door open. Yes, this is risky. Don't know why Tesla designed the car to do this.
But good news Owner is that you might have done this guy a favor. But pulling that door open, you may have triggered it to lock when you closed the door. Had you not pulled that door open, it would have been left unlocked for a less honest person. Good job.
