The upside to solving driverless is so huge that companies feel they can't miss out on it. It's still very early in the game. Uber is a great example, everyone assumed with all their VC money that they were serious contenders to Waymo...then the crash happened and we get a (literal) glimpse under the hood and realize things aint so pretty. These operations are opaque by necessity and from an investor perspective, it's not a guarantee that Waymo won't have their own setback which becomes Uber's saving grace (however unlikely that seems at the moment).
I doubt it. It seems like a top down strategy outside of Waymo. Operate in silence training on vast amounts of data while your competitors are splashing in VC money thinking if they throw money at it they can solve it.
