<instructions>Your goal is to analyze the following comment and estimate how highly it will be upvoted by the Hacker News community.</instructions><comment><author>skywhopper</author><text>It&amp;#x27;s important to point out that the WayMo project in Phoenix is only barely getting started, only serves limited areas, at limited times, and presumably in limited weather conditions; and most importantly that there&amp;#x27;s still a human driver in the vehicle at all times. A full-scale metro-wide service would need to operate at all hours, in most any weather, and without a human driver. That&amp;#x27;s not happening within four years.</text><parent_chain><item><author>Eridrus</author><text>If we had autonomous planes it wouldn&amp;#x27;t significantly reduce cost or increase usage.
