low-volume models

How convenient for companies that do that volume. The customer is at an auto show and he says "I dunno about this convertible. No roll bars. No safety cage..." and the lying grifter-salesman says "Oh, it's safe. It's very, very safe. I own one." And he'd never even get in one because he knows it's a deathtrap and it's never been tested.

So I would expect it will eventually? Maybe?

My hunch is that it won't be tested until there's a (horrible) death and the lack of testing becomes a scandal. Then the media will breathlessly say to it's audience "Most of the vehicles without NHTSA ratings are low-volume models. But we were surprised to learn that some other vehicles aren't tested either. Who knew?" You! You're supposed to know! You're supposed to learn about this sort of shit and report on it before deaths and maiming. It's your fucking job. Stop following Trump around 24/7 and covering Biden's brainfarts and do your actual fucking jobs!
