Tesla is still more consumer-friendly in this respect than any other car manufacturer I know of. You have to pay for map updates in most other cars... it's not cheap either.
Tesla's the only car manufacturer selling vehicles that supposedly have full autonomy hardware with full autonomy itself a near-future firmware update away.
That becomes meaningless hype on a whole new level if the many owners the Tesla rep acknowledges have stated a need for this can get firmware updates but not map updates.
I'm shocked that the complaint comes from the SF area of all places, there is probably a higher density of WiFi there than anywhere else on the planet.
The updates can't be triggered by the user, so you have to leave your car somewhere (or your phone in your car) for a extended period of time to hope to get an update.
There's also not free public parking everywhere (much less free public parking with WiFi coverage), especially in the urban areas where “my parking is remote from my living space and doesn't share wifi with it” is most likely to be an issue.
Also, outside of certain urban areas (and this can still be a problem outside of urban areas) there isn't free public WiFi everywhere.
