So, we came from a Prius and their locking system was so easy to use that the locking system in the Model S just doesn't cut it. I have one software tweak idea that might help, but I'm wondering if anyone else has any ideas. Here are the various failed scenarios: 1) My wife puts her purse on the floor of the back of the car with the key inside. The car autolocks. She has to dig out her cellphone and unlock the MS. 2) My wife is unloading the MS, hauling stuff into the house and the car autolocks on her. She has to go back inside, get her purse, haul it by the car, to get it to unlock. There are more, but variations on the above. Bottom line - autolocking is not what we need. Of course, turning off autolocking means that she has to dig through her purse and find the fob and click it. The small button on the door handle of the Prius was infinitely better. It is a little easier on me, as I carry the fob in my pants pocket and so the MS detects that it is in the car (in the front seat) and is easy to click in my pocket to lock. Fixes that Tesla should consider: a) Make the detectors stronger so it can recognize a key in the back seat. b) Have some kind of way of locking the car from the outside without pushing a button, as long as it recognizes that a key is present. c) A software fix - if autolocking is turned on, DO NOT AUTOLOCK when the MS is at your HOME location. This would be an easy software fix with an option that you could turn on and off. Whether it works in practice (like what if you park it outside of your house and not in the garage), I don't know, but it seems like it would solve our problems. Any other ideas? Bob.
