The sidewalk cluttering is such a non-issue. The real problem is people riding them on the sidewalks, which is annoying and best and dangerous at worst. Riding them in the street, on the other hand, is scary, I'm pretty sure too scary for mass adoption - I'm pretty sure Bird knows this and is hoping that people will be able to get away with riding them on sidewalks.
Edit: when I say that the sidewalk cluttering is a non-issue, I just mean that as far as I can tell there is barely any sidewalk cluttering, not that said cluttering wouldn't be an issue if it was actually happening.
