Tesla and "overnight success"

I've been thinking a lot about "overnight success" lately. Check out how long it's been taking for Tesla to achieve theirs! [Data collected by combining various public data sources. I might have screwed it up, but I think I'm mostly right.]

Of interest:

• Wow, they really didn't sell very many Roadsters.

• Recent increase in units/employee, probably due to better factory automation

• Miles driven since the last (reported) autopilot fatality is more than 2x as many as before; they're either getting luckier or the software is getting better.
