Another one: someone buys a sports car and promises to drive within legal speed limits at all times.
IMO that's a little different since many of them also buying the utility of appearances, which be flaunted at entirely legal speeds or even while parked.
In contrast, an expensive speedy car disguised as a cheap slow one would be much more suspicious.
"and my successors will all do the same"
You can buy fancy sports car for looks and status.
A better one: the large number of individuals who drive super-duty pickup trucks only for commuting to their office jobs.
