Why doesn't Tesla advertise at all? I'm just wondering.
Because it cost money... Elon on TV is the best advertisement and is free. Telsa spends money on super chargers = advertising and store galleries = advertising.
because they are supply constraint. Why generate more demand if one can not even satisfy current demand?
Tesla Model S on the road are the best advertisement.
No need yet
Why waste money advertising when you can sell all the cars you can build? Plus they get so much free publicity from the press, why pay for it?
The best (and hardest to obtain) publicity is free publicity. Tesla gets some by natural newsworthiness, and some by "staging" events. Doing it pretty well, so far.
