It's a long bike rack like this:

There are a few of them (3-4) lined up at this location.
I won't be making an official complaint (not sure to whom, anyway) since I did easily find a spot.
But when there are more e-bikes and it's a nice day it can be more challenging at this location as 3-4 e-bikes locked sidewayscan easily take up half of all the space there.
I also wonder about the feasibility of post and ring for locations like this. On a downtown street you can string a bunch of them along the sidewalk for the whole block. But at an office building, a mall or an educational institution (basically anywhere in a "campus" setting) you'd need more than 20 of them to do the same job as just 2-3 of these standard linear racks.
