They can die on this vine, by sticking with AVs. It will make it a bit more challenging to come up with a viable routing solution, but the same complete streets process should be attempted. I would think, they would need to lose a travel lane, reduce the remaining lane widths, add the transit lane adjacent to the sidewalk, then shift the parallel parking to be located between the travel lanes and transit lane. A traffic separator would likely need to be installed between the transit lane and parallel parking. Depending on the width, their transit lane could probably double as a separated bicycle lane.
