Improvements come from every car manufacturer, yet every car manufacturer is not experiencing a 50% drop in sales.
Sounds like you have a vested emotional attachment to electric cars.
25% increase in electric range, 25% increase in seating capacity, 10% increase in fuel economy, and an expected few thousand dollar price cut to boot. Care to give an example of another car that has offered a comparable level of improvement, while at the same time reducing the price, while at the same time not experiencing a drastic drop in sales?
Or do you just want to make personal attacks?
