Interesting, but could be better thought out. Why does he assume people would be generous enough to crowd fund autonomous cars, but not generous enough to crowd fund emergency drink delivery? Or even non-emergency drink delivery?

Depending on how smart those autonomous cars are, they might crowd-fund advocates so they have legal protections against being scammed by humans. Or humans who like autonomous cars (either like them because they're a valuable service or because the humans are fans of autonomous cars) might crowdfund advocates.
