> revolutionary things

Even if they make this work, what exactly is it revolutionizing?

Every generation of high-dollar sports cars has had something you could point to and say "that was way ahead of its time" or "they pioneered that." A few examples: fuel injection in the 1950s, variable valves and CFD the 1980s-1990s, dual-clutch transmissions in the 2000s, hybridization and electrification more recently.

You cannot tell me with a straight face that 20 years from now, my commuter will be outfitted with cold-gas thrusters and fans sucking it into the pavement.

Supercars have always been gaudy playthings for the wealthy. I think the difference is that Tesla doesn't even pretend the Roadster represents anything else.
