Okay. I'm new. We've all been there, so don't give me a hard time. I've also come from a history of driving Jaguar XKR sports cars. I know life's tough! But I'm used to a highly evolved and refined form of driving. Albeit with petrol! (How evolved is that you say!) So the keyless system I'm used to from Jag, like Pavlov's Dog, when hopping out of the car is - turn the motor off, get out, press a button on the door handle to lock the car - it beeps once to let you know all is right in the world and you walk off. If it beeps twice, you've done something wrong - like leaving your car key in the car - derr - and you fix it and try again. So just the other day, as I'm getting used to this wonderful new beastie of mine, a beautiful Obsidian Black 85D, I pull up and park. Managed that okay. Put the car gear into park to turn my Tesla off. Still not used to this - I can still feel a phantom engine hum. And got out and walked away, knowing my car would lock in seconds. Unfortunately, (wait for it, we all know what's coming ...) I had left my key fob in the car and it was never locked. On my return I wondered what I did wrong (besides the obvious). Clearly Jag got over drivers being so, hmmm, stupid, by forcing them, through positive action, to lock their car. What have I missed?
