As much as I LOL'd and agree with the sentiment, this is almost entirely about politics, not infrastructure -- the only tenuous connection is that the political shithead happens to own a car company. As such, please try to resist the temptation to post more stuff like this here.
Edit to address some feedback:
Yes, !fuckcars is political, but that doesn't mean everything political is on-topic. If this had been about Musk interfering with CA high-speed rail, it would be unambiguously on-topic. If this had been about the harmful effects of those trucks on other road users, it would be unambiguously on-topic (although for the record, I dislike threads hating on any one particular type of car because they risk missing the point that all of them contribute to most of the problems).
But it was neither of those things. It was just pointing out the dishonesty of people who bought a particular product with a particular political connotation. The fact that the product happened to be a vehicle was irrelevant to the idea being conveyed. That makes it a good fit for somewhere like !politicalmemes or !enoughmuskspam, maybe, but not here.
