I don't like Tesla. A Tesla car isn't practical for me, so by extension it's not practical for most. Massive popularity and interest in buying them proves nothing about the future because I don't have one. Other electric cars failed after receiving public support, and therefore Tesla will fail. Even though nobody claims free charging is sustainable, I claim that non-existent claim will lead to failure, because it's impossible to change our current electrical infrastructure. Ever. And a decade into the future? That's crazy! We need to deal with what's in front of us for the next ten minutes! And after that, we'll do it again!
