So that is a distinction between your app and the Tesla app that allows for "riskier" behavior with your app.
Even if the above is not correct, and even if your app, Allen, and the Tesla app do offer identical functionality, the more I think about this, the more I think you should give some serious thought to just not including any summon option at all in Remote S. I know that is an even more drastic position than the one I took earlier, but hear me out.
People can sue for any damn reason they want to, and the person or company being sued has to spend time and money defending the suit. Unfortunately you've experienced that first-hand with the patent troll. Someone somewhere is going to damage their car or their garage or both using summon. Actually I expect many people will. Some percentage of those people will look to sue someone. Let that someone be Tesla! Why would you want to open yourself up to that possible exposure if it happened to be Remote S that they used instead of the Tesla app?
Again, I recognize your desire to provide the most functionality to your customers. But taking on this poitential risk is, I think, above and beyond. I don't think you'd lose any potential customers by not offering summon. I would hope that your existing customers, and certainly your friends here would understand your need to limit your potential exposure. Yes, that exposure may not be any greater than Tesla's, but Tesla's pockets are deeper than yours, and they have a lot more to gain than you do. You just don't need to give us this functionality. Look out for yourself on this one, which, by the way, is also looking out for us--your customers. Because if a lawsuit down the road makes you pull Remote S from the market entirely, that would be a heck of a lot worse for everyone than simply not being able to use the summon feature from within it.
Please give this some serious thought!
