Ordering a taxi after running outside of US? Probably missed some mass transport. Raise the price boys... like good old Uber back in the day based on iphone battery level. Really the possibilities are endless if you're evil.

Bad health? Raise the insurance premiums? Or anything more evil I can't think of.

edit: grammar

None of those things sounds like stuff the government would have a hand in, unless you live in some communist country where the taxis are state-owned?
