The fact is, that number 1 EV car, Tesla Model S, is selling all that they can produce, and they are currently selling to less than 1/5 of the world. (using google cache since site is already /.)
Why are their cars in such demand even though they do not waste money on advertisement:
1) It is a luxury car with extreme performance.
2) the constant update and electric dashboard captivates everybody that drives it.
3) the ownership issue is finally being realized and ppl are learning that the costs of the tesla is much lower on the backend.
4) the fastest superchargers are being built all over Europe, America, and parts of Asia. These allow for free charging with 150 MPC done within 20 minues and 220 MPC done within 60 minutes.
5) all of the innovation is in this car, as opposed to having little innovation.
6) most of all, ppl like the 250 MPC. The idea of only getting less than 100 MPC and not having a super fast charger around DOES bother a lot of ppl. And it should.
Chevy volt, nissan leaf, i3, etc are all pure POS in which the car sales have been going down, not up as expected. In general the leaf and i3 are too weird looking and offer equal or less performance to ICE cars BY DESIGN. Interestingly, all of the electric cars could EASILY blow away ICE cars. Why do they not? Because it would gut the sales of ICE so, none of the car companies want that. However, all can see where Tesla is headed. Basically, they will be a major car maker (as in top 5) within 10 years.
