Could use some work. Voice to text works fine, but NLP and inference is weak.
Example: tonight I couldn't figure out how to use the windshield washer. Kept pushing the left stalk button, but didn't realize it had a detent, and a light press-hold wouldn't activate it.
I tried multiple different voice commands to get help, but all it did was launch the home page of the owner's manual. That distracted me from driving while I tried to navigate through the very long index. Finally had to pull over and scroll through to find what I needed.
Any voice command with an item in the index plus the words "manual", "instructions", "how do I", etc, ought to launch the appropriate manual page and read a voice summary. The query should not be overly sensitive to phrasing or syntax. Doesn't seem like that would be a technical challenge for a company as AI-centric as Tesla.
IMO this would substantially improve the driving experience and further differentiate Tesla from everyone else.
