It won’t be electric cars using the batteries, it’ll be ‘drones’.
If Harry Reid can keep China from making the batteries more cheaply.
Who cares if China makes the prices cheaper? The whole point of the giggafactory is to lower the cost of batteries. Either Tesla will do so by itself and reap all the profits (unlikely) or it will induce the market to lower costs and make more money by selling more cars. As long as Musk is right about how cheaply he can make batteries, it's a win-win regardless of what the Chinese do.
