After purchasing the fobs with higher encryption and learning that these not block a relay attack as I had hoped, I will either shrug and ignore the issue because it is rare and probably non-existent in the US so far, or maybe use PIN to drive if I get paranoid.
But what I won’t do is give up on passive entry or put the fob in a pouch, because that eliminates the wonderful convenience of being able to leave the fob in my pocket at all times, never having to mess with it. It is terrific to be able to just walk up to the car, get in and drive away, then park and leave it, knowing that it will lock itself.
By the way, based on an excellent suggestion by a TeslaTap member, I even worked out a way to preserve the above functionality, and yet make it stay unlocked in the garage and stop presenting the handles when I am walking by: define a driver profile called “Home” or something, set that profile to turn off the walk-away lock and turn off the “auto-present handles”. You still have to remember to manually change the profile to “Home” when you park in your garage, but that is not too much trouble. When you get in and drive it away it will always switch to some other profile.
