Alas google has become useless for finding useful information so I hope somebody who still has the book can confirm.
As others said, Sidecar was technically the first to the "ridesharing" model
Zimride (lyft) started the first rideshare site. Unless you count craigslist ads.
My skepticism of self driving vehicles in general is in desert climates. I really want to see a self driving taxi the day after a blizzard in Chicago (or elsewhere in the upper midwest... or even NYC when there's a good storm) where on some streets two lanes in each direction become one, and intersections can become "well, I'm not stoping because the car isn't stoping, thankfully the other drivers understand this and aren't asserting right of way when things are slippery". Some roads are closed and the smart drivers are happily driving 20 under the speed limit on the highway behind a snow plow.
Until then, self driving really strikes me as more of a California or summer time thing.
They say they're working on it ( https://www.bloomberg.com/news/articles/2019-04-23/alphabet-... )
> Snowy conditions are a serious challenge for the laser-based Lidar and other sensors that self-driving cars use to see objects in their path. Waymo said it’ll start working to overcome weather issues in Detroit’s notoriously tough winter months.
but I'll believe it when I see it.
With all that said, I wonder if maybe Amazon or some self driving car startup steps in and buys them up for a lot less than it would to build that penetration. Can imagine your Amazon owned Uber driver bus picking you up, with half a dozen stops on the way, some people, some packages, doing the rounds. Things change, how will Uber adapt and more so, all those drivers on zero hour contracts, are just as easily laid off and much cheaper as well. Self driving cars are a case of when, not if as so much being done in the field, progress has become a hot competition and slowly getting there.
