If Doc Brown's time machine was real and posted here, HN would be complaining that it's noisy, unimpressive, not street legal, uninsurable, and attacking Brown's personal character because he's a dangerous nutcase.

Seriously, I bet these are the same people who were shitting on the Hyperloop!

The time machine actually accomplishes something. I fail to see what this accomplishes other than a very cool circus stunt. Straight out of fast and furious. Which is great and all, but not a production car.

You forgot the part where Doc Brown purchased parts for the vehicle through funding by terrorists.

Well this isn't real so that's not a very good analogy. I also don't think Doc Brown (who's also not real) was famous for committing fraud and lying habitually to manipulate the market.
