If the NHTSA doesn't want their stats in marketing, why not figure out how to make them completely worthless. Stars is way too marketable and deceptive to begi

  The NHTSA stars are adequate for their intended purpose - showing how well a car holds up in a crash compared to equivalent cars from other manufacturers. You just can't use them to make any conclusion about the overall risk of injury (which depends on the likelihood of a crash happening in the first place), can't compare them between cars of different weight classes, and can't draw meaningful conclusions about the relative safety of different five-star rated cars. Tesla did all three. The last one might need a little elaboration. The NHTSA battery of tests is relatively small and limited. The lower the risk of injury in those tests is, the more dependent the actual real-world risk becomes on all the scenarios they didn't test. This isn't a hypothetical problem. The Model S also got the best score ever in the NHTSA tests and Tesla did a similar press release about that, but it didn't get the IIHS's highest rating because it performed badly in small-overlap collisions which weren't part of the NHTSA tests.
