You do realize that they're not at all comparable, right? The Roadster was a luxury sports car (and having ridden in one, it is
batshit insane how fast it is), and it's priced in that range. They're hand-built. They were never meant to be a volume car, they were meant to build a brand, which they've done quite successfully.
Now comes the second phase, where Tesla makes a luxury sedan that seats 7 and has the 0-60 times of a 500 horsepower BMW M5. I don't know about you, but I plan on buying one as soon as I can, and I bet a lot of other people do to. I wouldn't buy the Leaf at half the price, because it has an unusable range. Model S doesn't have that problem.
