We can quibble over the exact numbers... here is an article from InsideEVs on the value of the network. $154M as of September 2015. I don't know if the number of bays is linear to the throughput... maybe a mathematician or statistician can answer that but Elon has stated that the size of the network will double in the next two years... that was BEFORE they accelerated the production schedule. Also consider that aside from the difficulty of collecting sufficient revenue from use... you're also collecting revenue from FEWER cars to prepare the network for FAR FAR more cars. It's like trying to make social security work in reverse where a small population funds a large growing population. I don't know what the right number is... admittedly it's probably cheaper per car to build a nation-wide network for 1M cars than 100k cars. Yes... I think we can ALL agree (well... perhaps not ALL of us...) that local use needs to be discouraged but please separate punitive actions to mold behavior from what needs to be a source of revenue.
