Tesla is today the most valuable automaker in the world by market capitalization beating out industry giants like General Motors, Ford, Volkswagen group, and even Toyota. 
It has achieved this impressive feet despite a short operating history, a limited product lineup, and even relatively modest sales figures compared to these much more established entities.

So what is going on here?
What do investors see in Tesla that a rational person may not?
What is the companies vision to truly justify being valued this highly?
and could this all be a charismatic CEO taking a pool of naive investors for a ride?
