Or if you walk away with the keys it will lock itself. Too bad about no comfort access though.You're correct about it being like Tesla when getting in and driving off. The difference is when you're leaving. You have two options.
1. Park the car, get out and lock the door. The car will turn off but the comfort exit will not activate.
2. Park the car, hold the power button for 3 seconds, get out and lock the car. The comfort access will activate.
