The "main difference" is that Waymo wouldn't even try to drive coast to coast.

Because it's geofenced to shit. Restricted entirely to a few select, fully pre-mapped areas. They only recently started trying to add more freeways to the fence.

You're right, they wouldn't try, but I don't think there's any evidence for the idea that Waymo couldn't pull this trip off now from a technical POV. Even if they're pre-mapping, the vehicles still have to react to what's actually around them.
