This is really cool, and is obviously intended to be just the beginning of something that could be really amazing.<p>I suppose this is mostly just Tesla wanting to "beta" test the technology & collect some data to work with for future optimization...<p>I just don't see the practicality in this specific functionality that they're rolling out -- sure, it's neat, and I'm sure many of us would love to show it off to our friends for the wow factor.<p>But right now, you pull in the driveway, and tell your Tesla to park in the garage. It opens the garage & parks. Now what? You've got to follow the car into the garage & plug it in to your wall-attached charging cord.<p>Same thing when you leave the next day -- you've got to unplug the cord before you summon it to the driveway ~20 feet away...<p>Neat for sure, though. ;-)
