Sounds like the issue is that his car was previously damaged. Tesla knows about that and for liability reasons doesn't want him supercharging.
I'm sure someone is concerned of the possibility of his car bursting into flames during charging because of physical cell damage.
That is... Not a bad thing to be concerned about.
A dozen years ago or so there was a huge uproar about "common core" mathematics, which was a new standard being used in the USA for teaching.
It was a politicized trendy topic and even so-called-intellectuals were jumping on the train and calling it a deranged way of learning math.
I looked into it a bit, and I swear this pic pretty much sums up one of the key methods they were teaching.
Basically just tricks that a lot of people figure out to simplify problems.
