Evidence suggests that none of this is true. Just look at how Google Fiber wasn't able to navigate the myriad regional regulatory roadblocks thrown up by local governments when lobbied by incumbent ISPs. It's reasonable to expect exactly the same scenario to play out if Google tries to make a competitive ride sharing service from scratch.

That's a pretty good example. But in the case of Fiber, part of the problem was that other ISPs own/control infrastructure (like poles) to which they're legally obligated to give competitors access...and they would just not comply, or drag their feet on it. Fiber physically couldn't execute because of this. Of course there was corruption involved, as you pointed out, but in the case of ride share apps I can't immediately think of anything analogous, where Uber could physically prevent Waymo from competing with them.
