I've also filed a NHTSA report, some 12 months old now, that has been greeted with ... crickets. Something very basic, that any car maker should be able to do, is write a manual that teaches people how to use the (poorly written) software.

The manual explains that you can do a 3-step invocation of a voice command: 1) push 'voice' button; 2) utter command; 3) push 'voice' button to complete. It hasn't worked that way since 2019. See, e.g. Software version: 2021.32 [1], p. 161

Good luck teaching people how to use 'Full Self Driving' with these kinds of error checks.
