We had this in the Netherlands in 1999. I think its still in operation today. I used to work in Rivium business park at the time and used to ride it every morning (when it worked).

That's neat, but not only does it need a dedicated guideway, they even have crossing gates where it crosses streets.

As these things get smarter and can share with other road users, they'll need less dedicated infrastructure, which makes them much more useful.

But that one is low-tech, like the automatic robots in factories. It uses magnets under the road surface and RFID tags, see FROG link on the wiki page.

The OP article mentions high-tech sensors like stero cameras and LIDAR -technology that requires state-of-the-art computers and is used in Google self-driven cars, etc.

And?... if the end result is the same? :)

One requires expensive road infrastructure, the other doesn't.
