What's most interesting to tech enthusiasts is the fact that the middle panel seems to be one gigantic screen. Is it touchscreen? I damn well hope so.
The pure electric car manufacturer has already delivered $100,000 Roadsters, which are fun to drive, but get into accidents easily. (I saw one myself last week.) Even Governor Schwarzenegger wants to return his, but only because he's slightly too big to fit. The S, on the other hand, can be quite an interesting step in electric car design and manufacturing of Tesla actually manages to deliver enough of them to service more than just a niche market.
By the way, the price is only $50,000 once you factor in the $7500 in tax credit. It actually starts at a base price of $57,400.
