A lot of people in the industry really underestimated the difficulty in getting self driving cars be effective. It is relatively easy to get a staged demo together, but getting a trustworthy product out there is really hard.

We've seen this with all of the players, with many dropping out due to the challenges.

Having said that, there are several that are fielded right now, with varying degrees of autonomy. Obviously Waymo has been operating in small-ish geofences for a while, but they are managed >200% annual growth readily. Zoox just started offering fully autonomous drives in Vegas.

And even Tesla is offering a service, albeit with safety monitors/drivers. Tesla Semi isn't autonomous at all, but appears ready to go into volume production next year too.

Your prediction will look a lot better by 2030.
