Green cars have routinely been mocked in public, on TV, in movies. Small wimpy, boring, the exact opposite of what mainstream wants/desires.
The roadster is changing that. People complain it is for the rich.... Guess what even if it only cost $10,000 they still wouldn't sell anymore. Right now they are capacity constained. They sell every single unit they make months before it is produced.
So selling an EV for less would simply mean less money to imrove the product.
Tesla has a smart business model IMHO
Roadster (2008) = $100,000 ea about 2,000 produced annually
Model S (2011) = $50,000 ea about 10,000 produced annually
"BlueStar (2012) = $25,000 ea about 10K-20K initially and plans to ramp up to 100K annually.
This it he Model S:
More like a Sports Sedan. It "only" does 0 to 60 in 5.9 seconds (vs 3.7 seconds in Roadster).
If Telsa had tried to go right to the BlueStar (codename BTW) they would have failed. They have made mistakes, and learning things along the way. Much easier to recover from mistakes on 2,000 units with high profit margin then on 50,000 units and low profit margin.
