I don't disagree, but this reminds me SO much of when I bought my first Mac in 2002 (mind you, I was switching from Linux, not from Windows) and all the nay-sayers were claiming stupid stuff like "MAC doesn't have virus problems because who writes viruses for 2% of the market?" My basic attitude was "I'll enjoy what I've got while I have it."
I've only OWNED a Tesla for 6 months, but man it feels like the other manufacturers have been about to release a Tesla killer Real Soon Like Now for a whooole lot of years. I certainly don't think Tesla's lead is insurmountable, but it sure seems like the competition is doing its best to drop the ball.
