Doesn't obfuscating the location of the defroster control run afoul of the NTSB safety regulations since a window defroster has been required safety equipment in all cars since the early 70s?

Relevant statute: https://www.law.cornell.edu/cfr/text/49/571.103



Statute inherits from SAE J902A which costs $89 to read, so we don’t know from the statue alone.

Even if they don't explicitly say it has to be an obvious button on the dash, it's a huge liability changing how basic safety equipment is operated.


That seems like it's more about how well the defroster should work, but says nothing about how it should be activated.


Yes. The defroster is basic safety equipment.

If your smoke detector manufacturer changed how the test button worked with an over the air update, and as a result you failed to correctly test it, who would be liable?

Much in the same way, if someone cannot figure out how to use their defroster because a UX engineer decided to make it just so, the Tesla owner just drives off with a mostly iced up windshield because, and the Tesla owner gets into a crash because it's 7:00am on a cold winter Monday and they're running late, does Tesla share some liability for changing how basic safety equipment works?


> does Tesla share some liability for changing how basic safety equipment works?

If I was on the jury for that specific fact pattern, then it seems very likely that, yes, they would.

Probably the lion's share of the liability too (though definitely not 100%).
