@theologyandfishing EV's are a race to the bottom in price, as they are a simpler machine and the production of batteries will not be limited to the automotive industry. The larger volumes will be in the storage industry, and so battery advantages in cars will be... non-existent 30 years out, likely non-existent 15-20 years out for the auto industry. I.e. Tesla is unlikely to be the leader in low-cost battery tech alone in 15 years. They already are not the leader, they just have the most volume (which is definitely impressive, don't get me wrong).
So for the EV angle, expect lots and lots and lots of competition and a race to the bottom. Drive chain especially.
#2 Self driving: as a software dev, they're in for a rough ride, and may not see large scale adoption for 20 more years. Just so many millions of corner cases. It's already getting hard and they're not even close to better than most 16 year olds.
#3 The only thing going for tesla's valuation is the battery storage angle and becoming a massive scale manufacturer and mining company, etc. While they can definitely get there, it wont be with a 30 forward PE. it would be capped at world energy usage per like week, maximum. So calculate total world energy used annually, reduce it by 30% for efficiency gains from going electric, divide by 50 to get a weeks worth, and calculate how many batteries that will take. Then divide by 50 years to get a steady state amount of demand, and then estimate the per Kwh price, which is likely $10, of which is $1 in profit, and tell me what you come up with.
