Seems to me to be dependent on how the incentives line up.
A credit bureau WANTS you to part with any money you might have for a car. So it works out when they control the issuance of your loan.
But would you want the NRA to control the social credit system regulating a firearm purchase?
I prefer that to Chase controlling it: https://www.sec.gov/Archives/edgar/data/19617/00019768782300... (the link details an instance in which Chase was alleged to have debanked a bipartisan, multireligious charity headed by a former U.S. governor, senator and ambassador). The NRA would probably let me buy the gun, after all!
If you read the comment, you’d notice that there were no loans involved whatsoever.
If you can’t rent or buy a car without a credit score, you should only be allowed to buy a gun until you have proven that you’re a trusted member of the society.
