Of course here on this forum we'd like to imagine Tesla is showing the way forward -- but the rest of the car industry is looking at the numbers of around 50,000 Teslas sold versus over 3,000,000 Priuses, and are laying their own plans accordingly.
Tesla is carving out their own niche by building luxury/performance EV's. So they shouldn't be chasing Toyota-like volume. Don't get me wrong they need to increase sales but lets be realistic.
