Head of the pack of dreams maybe. What does Uber have, in a tangible manner, right now? At least both Tesla and Google have real systems that are on the verge of full autonomy.
I know they gobbled up a bunch of researchers, but moonshot engineering feats like autonomous driving is not (yet) in their DNA. And their current business model is not profitable and will die the moment they go up against an autonomous service.
They don't need to be last to market to lose, they need to be first in order to survive.
Except for the fleet of Ford Fusions and XC90's covered in very nicely implemented custom sensor rafts http://theincline.com/2016/12/12/three-months-of-self-drivin...
