Today I learned. The Tesla owner's manual has alt descriptions for its images. They're not good alt descriptions, but they are there.
In fact, it is one of the most screen reader accessible manuals for any device I've ever seen, most are some weird PDF abominations where all the button names are replaced by their unlabeled icons. Even devices made specifically for the blind have these issues sometimes. This? This is just perfectly readable HTML.
It's especially ironic considering that Teslas (as far as I know) aren't accessible in any way. Even the infotainment system, which a blind person might want to use, for example when waiting for a sighted acquaintance in the car, does not have a screen reader and is not in any way usable.
If you're curious, the manual is here https://www.tesla.com/ownersmanual/model3/en_us/
