Reply #6: It boosts research

[Juche]

The good thing about a $10 million prize is that companies spend far more than that in research to find ways to achieve it.

The X-prize for space flight was $10 million, but companies invested $100 million in research & development to try to win it. And that R&D can still be used.

So no matter who wins this prize, tens of millions of R&D will go into trying to win it, and that is a major benefit because that R&D can still be used to create the next generation of cars.
