Lamenting the difficulty of registering kei trucks is kind of rich coming from the patron saint of "the roads are horribly dangerous and we need to do everything to safen them up and drivers can bear whatever that costs"

Protectionism when I don't like it, public safety when I do I guess.

In any case, they're pretty easy to register if you don't lick the boot. Whatever state you're in typically isn't gonna come after you for tax evasion for an object they aren't in the business of taxing if you catch my drift.
