That's a bit silly. I suppose in someways it is nice for the consumer that they have the 60kwh version if they're basically selling it close to a loss with the hope that you'll pay for the battery upgrade, but obviously it begs the question why the 75 model can't just be the same price.

Because Tesla would make less off of each 75, which is no good when you need cash to expand operations. Have to squeeze every dollar out of each sale, manufacturing and R&D costs money!
