I went into this thread wondering why it's considered a problem
Then I realized I've driven 61,000 miles with the lock settings set to non-defaults
Every time I see another person with a Leaf, their lock behavior seems strange to me, and they'd always love me to tweak their settings (which I do).
Door button behavior: lock/unlock all doors
Auto-lock: on at 15 MPH
Auto-unlock: shifting to P, all doors
It just makes more sense to me, working in a day. I usually lock and unlock my car exclusively with the outside door button and "P" shift button. Probably thousands of cycles through the same routine... walk up to car, beep/unlock with door button, drive, unlock when I hit "P", beep-beep/lock with the door button. Someone needs to get in? Beep the door button. Dropping someone off? Come to a stop and hit P. Passenger doesn't even need to fumble for the lock button.
Should be the default, IMO.
