"R&D" sounds grandiose but what meaning does it actually have in this context? I think that's the bet on autonomous cars? Problem is, they won't be the only one to have them, and not even among the first and best ones it seems. Nor is it clear how anything but complete autonomy could solve their problems. Actually, not even if that actually worked it's clear why Uber's Über-ambitious plans would work out. As far as I can tell that "R&D" money is just wasted - but I'm mainly saying this in order to hear counter-arguments, not because I know (I don't really)...
