What are actually Elon Musk's engineering talents? It seems he is not much more than a marketeer. It's not even clear his visions of reusable rockets and electric cars were original...he is known to take credit for subordinate's ideas and achievements.
Cult of personality mostly. However Electric cars are actually useless for the environment without renewable energy. So it probably made sense to save Solar City. This whole thing seems like a long term plan for building an absolute monopoly - like what would happen if oil companies also owned all the cars.
Isn't even a modern coal-fired power plant cleaner than the ICE in a car? It certainly isn't perfect to have fossil fuel sources powering the electricity used to charge a car, but I'd much rather isolate and improve CO2 capture at coal-fired plants over having 250+ million polluters spread out over the entire country.
