Great discussion here. I recently posted the following on another site:
Elon Musk recently said (last month), that "if he wanted to make a sedan with a 500mi range, he could do it now."
But from an affordability standpoint, it won't hit Tesla's target market. Thing is - I don't think we need an EV with a 500 mile range - ever. That's about 9 hours of continuous driving. Most people only need to drive 9 hours per day, maybe several times in their entire life. Why pay a premium every day for a task you need to fulfill once every few years (on average)? The household that only has one car could rent an ICE for those occasions and come out far ahead.
