With every single other car I've owned (or know of) there is a physical lock/unlock button that is quickly accessible. With the Model S, you can lock it with a few navigation clicks in the UI, or fumble around for the key fob. Or, take even longer to access the Smartphone app to lock. Does anyone else know how to quickly lock the car upon entering? I'm thinking about this from a security standpoint. Also, auto-presenting ONLY the driver's door handle would be a nice selectable security feature.
