Battery tech
Tesla don't own any important battery technology or patents.
Main battery manufacturers are Panasonic, LG Chem and Samsung SDI. Panasonic is the leader and Tesla’s manufacturing partner, but LG Chem has made lots of progress and they are supplying to GM. Panasonic is rapidly expanding their own battery production is going to sell to other manufacturers also.
fixed cost and mass production
Tesla has no experience with large scale mass production (producing less than 100,000 cars annually is not big league). They have struggled with quality and delivery even with modest volumes for years, it will be harder when volumes grow. They don't survive massive recalls if the quality is not improving.
They have to get Model 3 into mass production within a year or they will run out of money and investor's and customers patience. Nobody want's to wait years for a car. Roadster and Semi are just distractions. Tesla's future is on Model 3.
The only reason this is seen so negatively right now is mainly because Musk has set such high standards for Tesla by trying to increase production by 5x within 12-18 months and hoping everything will go perfectly smooth.
