Agree, it's perplexing that Waymo thinks it makes more sense to start mapping out NYC rather than making the product work in Phoenix or SF. You could interpret this as confidence, i.e. they're so close to a working service in Phoenix/SF that they want to lay the groundwork for NYC right away. Or you could interpret is as a lack of confidence, i.e. they don't have much progress to report, and they're positioning that as "the reason we don't have a working product yet is that we're trying to solve the whole problem at once, and that's really hard."
