Eccentric billionaire and Tesla founder Elon Musk wrote an update blog post about the future direction of the self-driving, electric near-luxury car brand. Musk was adamant about solar energy, which will lead to sustainability for the human race. He also emphasized the autopilot systems, and a feature where owners synchronize their car with a Tesla phone app, and pay for the car only when the Tesla is in use. Musk has big dreams and big pockets, and he never fails to entertain.
