Yes, but the point is it doesn't need to be ready for 100% of locations immediately. Los Angeles alone has close to 19 million people. Add in other favorable cities like San Jose/SV, San Diego, Las Vegas, and Phoenix and you're looking at a fair portion of the total US population. You can have robotaxis serving those cities initially while the technology matures, and location-restrict autonomous driving for consumer-owned cars to the same places. People seem to think that the moment autonomous cars hit the road, they need to be able to handle a blizzard on a dirt road in upstate New York, but that just doesn't make any sense.
I think autonomy will be partial, conditional, and thus not door to door autonomous for at least a decade.
I sooner expect Alphabet to sell this tech to a big 10 auto manufacturer, or to Apple, for the same reasons as Boston Dynamics: where's the cashflow? If it's not up for sale in 5 years, I'll expect it's the real deal and we'll see door to door in another 10 years.
