Man, I didn't realize that article was written in 2013, it could've been written today, and it still would've been true. I think one of the biggest contributions to the tech illiteracy of people is, 1. Schools don't really teach you about that kind of stuff (in my experience, or unless you take a special course) and 2. Everything is basically done for you now, its incredibly easy to do anything basic on computers.
For a truly unobtainable car, I’d say the GM EV-1.
