The issue isn't size of the testing suite, it's covering all the edge cases. Some rather common edge cases go ignored. Unless they've updated Waymo in the last couple of months, they still fail to distinguish when they have a reserved destination lane when making right turns, as exhibited when going from eastbound Central to southbound Castro every damn day (before Castro was closed). Self driving system vendors can claim that fewer deaths will occur with their system vs the average driver, but that mostly reflects how dangerous the "average"/distracted driver is. Those numbers are little comfort to the loved ones of someone killed in an "edge case" that a competent driver handles without injury.
