I'm a little confused. What part of this is actually dumb ?
"Our most important assumption is [demand for] electric vehicles, given the battery-cost declines and the new chemistries coming out of Tesla. We believe the average electric-vehicle price will drop below the average auto price in the next two years. In five years, a Toyota Camry will still be around $25,000, but a 200-mile-range electric vehicle will probably be $15,000."
Are you saying the price can't go down to $15k in 5 years ? For eg., can a Chinese company make a $15k car with 200 mile EPA range in 5 years ? Or are you saying Tesla won't have a $15k car with 200 mile range ?
ps : A long time back I coined my own "evnow's law", which said the EV range will double every 5 years for the same price. Between 2011 (74 mile Leaf) and 2016 (230 mile Bolt) - for similar price we got 3 times the range.
