I actually have seen plenty of people that could have done something like this, but did not because they simply never tried. Being daring by itself is a skill, but we're talking raw technical ability here.

I've actually seen another developer that was probably in the same category write his own self-driving software. It kind of worked, but couldn't have ever been production ready, so it was just an exercise in flexing without any practical application.

So, what product that George built do you actually use?
