I'm not a Tesla owner....just Tesla-curious. So I'm hoping you guys are more dialed-in, and can clear up a few things. 1. I know specifics haven't been announced, but is there informed speculation about how much range might be extended via factory-installed solar (on super sunny days as well as normal days)? Just so I can get a general sense of it? 2. I don't totally understand the paragraph about buses, especially " would also take people all the way to their destination. Fixed summon buttons at existing bus stops would serve those who don't have a phone." I'm sure someone out there has already fleshed this out....can anyone toss me a link? 3. Musk seems narrowly focused on # of vehicular deaths as THE metric re: autonomous driving. But anyone who's ever participated in the cat/mouse game of street-crossing in a place like Manhattan knows that if cars predictably brake at any cost to avoid pedestrians (as they obviously must), pedestrians will hold god-like control over traffic. I.e. if we remove the element of fear re: driver inattention/incompetence which maintains the delicate pedestrian/car equilibrium, urban driving will be unviable, no? More general question: when praising the green-ness of electric, everyone hastily notes that, of course, electricity generation isn't totally green, either. Can anyone give me a Twitter-length contrast of carbon footprint for electricity versus gas, in terms of overall national average (I understand there's varying % of wind/solar/coal/etc in different parts of the grid)?
