combustion engine cars convert 15% of the chemical energy in their fuel into forward motion. The tesla gets 88% of the energy in its batteries in foward motion. Sure, theres efficiency losses in electricity transmission from a power station to a car charging point, but electric opens up the possibility of using alternative energy sources, like festooning your roof with solar panels and charging with those. the tesla uses energy over 4x more efficiently, from more sources, and you say that dosent change anything? Your wrong, and you should stick to 'summarizing' things you know something about.
and we care about his opinion because he heads a successful electric car company. pretty fucking relevant if you ask me. more relevant than your opinion.
