except for being like 10x more expensive, of course
> easier infrastructure build out
lol yes we should just replace Amtrak with 40 lane highways full of waymos. great idea
You must not live in a dense city. Rail doesn't have traffic and is usually faster, and much faster in heavy traffic, including rush hour, sporting events, airports, bridges/tunnels across the river, parades, marathons, etc. etc.
Also, there's no advantage to Waymo that doesn't apply to rideshare and taxi. I doubt people will care that Waymo vehicles autonomous, beyond the initial novelty (and despite SV's attempted marketing that their robots are better than people).
Finally, despite SV trying to ridicule any attitude that threatens their profits, most people like the greater good.
It's also not true that there's no advantage to Waymo; I take rideshare and taxis everywhere, and it will be a massive draw turning that into a pure transaction with a robot instead of it being a potentially social experience based on the whims and social malfunctions of the driver you get that day. As soon as Waymo or equivalent is available everywhere I will never choose to take a human-driven car again. And that's before getting into the many traffic advantages afforded to a fleet of cars that act as a collaborative swarm.
To me that does describe the greater good. For all its real benefits, passenger rail is inflexible and bulky in comparison.
