NHTSA Tells Tesla To Stop Exaggerating Model S Safety Rating
cartechboy writes "There's always that kid in the class that ruins it for everyone when being graded on a curve. At the moment, that kid is Tesla and Elon Musk. Tesla's been proudly claiming the Model S is one of the safest cars in the word despite the recent fire controversy. And while it may be just that, claiming it earned 5.4 stars from NHTSA isn't pleasing the safety agency as there is no such thing as a rating higher than five. While NHTSA already released a statement indirectly to Tesla saying it doesn't release ratings higher than 5, Tesla continued to promote this fictitious rating. Now NHTSA has updated its guidelines explicitly stating safety ratings are whole numbers only and that 5 stars is the maximum advertisers can claim. If advertisers and automakers decide to disregard these rules NHTSA is threatening removal from the program or referral to state authorities for appropriate action. Basically, hey Tesla, stop making false claims."
My car's rating is higher than the maximum rating allowed by the NHTSA.
No sig today...
Stay tuned for Elon Musk's critique of the NHTSA and long blog post detailing why the NHTSA is a bunch of corrupt scumbags and how Tesla is so awesome that it is able to get ratings above a perfect score.
It got a 5.4 rating, but the NHTSA guidelines only allow them to advertise a whole number.
Liar liar car on fire!
If you like your Tesla safety rating, you can keep your Tesla safety rating.
Table-ized A.I.
Just to clarify, the NHTSA hasn't said anything to Tesla like the summary states. It has clarified its rating system. That is all.
That article is written like a high schooler's blog.
I think we've seen this before...
Elon Musk would never have accomplished what he has if it wasn't for his rabid passion and forceful, egotistical personality. He is trying to change the status quo in an industry where many have tried and failed, and where many want Tesla to fail as well. He had best try to temper himself, though; lest he become our generation's Nikola Tesla/Howard Hughes in more ways than one.....
Because the rating system isn't accurate enough to say for sure that .1 difference is accurate. The ratings are subjective enough that whole numbers are as accurate as you can get reliably.

Apparently people aren't reading what's been said. Tesla's press release says: "National Highway Traffic Safety Administration (NHTSA) has awarded the Tesla Model S a 5-star safety rating", and "NHTSA does not publish a star rating above 5". Thus Tesla is not claiming that they were assigned a 5.4 since they outright acknowledge that NHTSA doesn't publish a rating above 5. What Tesla did say is that if one were to take the individual scores that were provided by the NHTSA (which apparently includes ratings above 5, and possibly decimal as well) and average those, the resultant number would be a 5.4.
Now what is probably getting the other manufacturers upset is that the clipping of the results at 5 means that the vehicles that just squeaked into the 5 look the same as vehicles which may have blown past the 5. If they didn't like that, why aren't the individual scores also integral and clipped at 5? Then one could not possibly claim (or even appear to claim) a number higher than 5.
So, this whole release is trying to beat up Tesla for something they didn't say. They didn't say that the NHTSA awarded them a 5.4 rating (see the first quote). They did say: "achieved a new combined record of 5.4 stars.".
Sometimes you have to know when to hold 'em, know when to fold 'em, and know when to walk away.
Pfffff...... his sound system goes to 11 .4 , bitch!

As far as I can tell, Tesla claims - as do several news outlets - that the NHTSA also releases some other raw numbers to the manufacturers which Tesla then decided to 'combine' (whether that's adding or averaging or whatever - who knows.) to give a 5.4 .
Really, the issue is lack of transparency - since we, the public, don't get to see those numbers. Thus we can't really give a good opinion other than "NHTSA says 5 is the maximum. THE MAXIMUM!" and all nod in agreement at the overlord's words apparently for fear of getting booted out.
This in turn leads to gems like this:
"No matter what, you can't say it's the safest car ever tested, just that it had the best overall test score of any vehicle tested by NHTSA." - NHTSA ( http://abcnews.go.com/Technology/tesla-crash-test-rating-high-maker-claimed/story?id=20024779 )
So it had the best overall test score .. but is not necessarily the safest. But the test is on safety. So it's the best in safety.. but not necessarily the best in safety.
Maybe while they're quibbling they could come up with a system that makes sense to themselves, the manufacturers and, most importantly, the public. If in the end that means Tesla does get a 5.4 and they want to hang on to 5 stars - well I guess they'll just have to lower the rating on a bunch of other cars.
The next Tesla ad will claim a safety rating of 11.0 stars from the NHTSA (small print: National Highway Tesla Sales Association).
About 80% of the comments already seem to be talk about how the NHTSA actually did give them a 5.4, but only allows them to advertise whole numbers and nothing above 5. So... it's a technical dispute over bureaucratic assholery.

The Tesla, a vehicle, does not generate emissions.
If you charge it with carbon-sourced electricity, the Tesla, a vehicle, still doesn't generate emissions.
If you strap a diesel generator to the roof to run your personal electronics, the Tesla, a vehicle, still doesn't generate emissions.
If you load up the trunk with flatulent cattle, the Tesla, a vehicle, still doesn't generate emissions.
That some people have trouble parsing natural language is not Elon's problem.

"She'll make .5 past light."
"She may not look like much, but she's got it where it counts."
To play devil's advocate for a second, measurements like the safety ratings inherently have error to them. For something like car safety, is a 5.4 really better than a 5.3, or was that just a quirk of the particular tests they did, and the 5.3 would be safer on the road?
Look at it from the NHTSA's perspective: if you think that Tesla's advertising is making claims that aren't particularly supportable because of margins of error like that and they're using your data to do it (and in the process saying essentially "NHTSA says we're the safest car on the road" when you don't want to make that claim), I think you'd be well within the realm of reasonableness to make them stop it.
Not really.
What happens is cars are rated to the current safety rating - the reason you can score above 5 is because the number is based on the raw figures and the current weightings.
The NHTSA records down in its database the raw numbers, then uses those numbers to calculate the safety rating based on the current weightings (from empirical data). This lets them recalculate the safety rating as need be - yesteryear's 5 stars may be this year's 3 stars, for example. Or, depending on how cars individually perform, it's possible two 5 star cars with the old rating may become a 3-star and a 4-star car.
So you cannot compare "stars" between model years, but you can compare them with historical vehicles recalculated to new standards. After all, many old 5 star vehicles may lack the safety features present on today's modern vehicles, so they won't be 5 stars anymore in the current rating.
The rating will go down as new model years and new tests are introduced - after all, we'd have hit 5 stars 50 years ago if the tests didn't change. The NHTSA updates its tests and ratings when too many cars are pegged - and there's a new test that apparently reflect the more common crashes that many "5 star" cars now fare poorly on.
Next year, the 2013 Tesla Model S may drop from 5.4 to 4.3. But the 2014 Tesla Model S may still get a full 5 stars because Tesla anticipated the new tests and built the cars to withstand them appropriately.
