Admittedly, on a very limited basis. But there is one thing to consider: There are a lot of city cores where average speeds are low enough that such specialised services are viable way of reducing the need for fully flexibly autonomous cars.
These are also in actual use some places (though lagging laws means that many places there's still an attendant), and there are other manufacturers.
So while the full general purpose replacement may take longer than hoped, a lot of more special purpose vehicles like that will nibble away at transport needs, and illustrates that if we look at it as not a problem of replacing cars, but a problem of replacing journeys, it's possible to solve parts of it piecemeal long before we can fully replace cars.

E.g. here's an autonomous shuttle manufacturer:
