Nilay Patel (I'm gonna get this slightly wrong) has this story where he was talking to an airline CEO about standing-only tickets and the guy said "I know two things. If we did standing-only tickets we'd get roasted by the public, and those tickets would need the most popular tickets by far."

people pay a lot more for private jets which are comparatively a lot more dangerous

This would make for an interesting aspect of a dystopian future. Accepted liability as a slider basically. There would obviously be entire regimes around auditing the published numbers (since companies would be incentivized to make their options appear less risky than they are). Pretty anarcho-capitalist.
