what's disproven, that the hummer has a higher carbon footprint? got a source for that? it will really depend on your power source of course, most of which is generated by burning fossil fuels

Really, the idea of justifying this level of inefficient consumption blows my mind -- it has 250 kWh batteries! You can run a whole home pretty comfortably with just 10 kWh and a few solar panels. Why do you need to move 5 whole fucking tons of stuff just to get your ass from A to B when a bicycle would do?
