Fortunately it only happened once to me that a moving car hit my stopped car. I was sitting in it, saw it, and I wasn't really angry - well, I was a little - since I believed it was unintentional. However, if someone would remotely send a vehicle (Tesla or not) into my stopped car, I'd seriously consider testing in practice whether an honest shellacking cures stupidity.
You do not remotely operate any vehicle with a highly unreliable signal/remote. And you do not believe a function is "smart" if there's a version of it that's called "actually smart" unless you're actually simple as a shoelace.
