There are also ways to drive fast legally

Allow me to introduce you to sleepers which are somewhat expensive cars disguised as cheap pieces of shit. Most I've been in are absolutely terrifying but seem like lots of fun.

Based on how often I find myself watching laden work vans pass vehicles that can easily "do better" this, or something like it, is likely a common reason for purchase

Except in Germany!

(Technically correct is the best kind of correct)

I mean, every person who purchases a car does so, at least implicitly. The very act of obtaining a driving license contains an (often explicit) promise to abide by the rules of the road.
