Smart Summon Runs Into A Parked Car
The quoted repair bill seems very modest, less than $5k, so it tends to make me think the story checks out (though who can know these days I guess?).
It does seem risky, if you are not using it with a full view of any side of the vehicle that may contact another object, and you have not familiarized yourself with the lag and are not an expert experienced user.Your other contention that using this around other cars (e.g., parked cars) is "risky?" Sorry, don't agree.
I definitely think it can be used (personally I can’t come up with a use case, other than jousting with other Teslas which is fun, though stressful), but I also agree it should never be trusted, and that likely means avoiding use in some situations.
