Why bother doing anything at all with this attitude?
Let's freeze in place and wait until the sun dies out. I don't know.
To me, Waymo is exciting because it could unlock a next step function of capabilities, patterns, and economics. Everything we take for granted in transportation -- highways, traffic signals, parking, traffic itself -- we could potentially get to reevaluate a lot of previously-held assumptions. The second- and third-order effects could be wild.
Maybe it'll all go bust. It's worth a shot, though. The rewards, if they succeed, will be tremendous.
