I doubt Tesla does a single press release without Musk's approval.
I heard no one can flush a toilet without his say so!

But seriously, Tesla used NHTSA's own Vehicle Safety Score (VSS), that NHTSA publishes in the Federal Register.

While NHTSA’s New Car Assessment Program doesn’t distinguish safety performance beyond its 5-star scale, every car rated by NHTSA since 2011 is assigned a Vehicle Safety Score, which NHTSA calculates by taking the weighted average of the Relative Risk Scores (RRS) in front, side and rollover crashes. We compared the underlying and publicly-available NHTSA data for each published vehicle since this calculation protocol began in 2011 (dockets: NHTSA-2010-0164, NHTSA-2011-0085, NHTSA-2012-0055, NHTSA-2013-0053, NHTSA-2014-0043, NHTSA-2015-0034, NHTSA-2016-0045, NHTSA-2017-0037).

The Vehicle Safety Score represents the “relative risk of injury with respect to a baseline of 15%,” according to NHTSA. Model 3 achieved a Vehicle Safety Score of 0.38, which is lower than any other vehicle rated in NHTSA’s public documents. By multiplying the Vehicle Safety Score by NHTSA’s 15% baseline figure, we arrived at an overall probability of injury for Model 3 of 5.7%. Applying the same calculation to each of the vehicles rated in NHTSA’s documents, we found that Model S achieved an overall probability of injury of 6.3%, and Model X achieved an overall probability of injury of 6.5%, making them the vehicles with the second and third lowest probabilities of injury, respectively, based on NHTSA’s publicly-available data and records.

We respect that NHTSA only endorses ratings from 1-5 stars so they can be helpful for the public to make quick and easy comparisons. The star ratings are especially helpful to show on the Monroney window stickers of new vehicles that are offered for sale. At the same time, we used NHTSA’s own methodology and data to help further educate the public about important safety information.
If NHTSA doesn't want to compare vehicles in different weight classes, they shouldn't calculate and publish VSS' for them.
