The only downside I’ve discovered, at least in Chicago, is that funding for separated bike lines usually don’t include funding for separate snow removal.
Not that having the bike lane on the very edge of the plows path isn’t a mixed bag too. You’re as likely to get incidental clearing as you are incidental piles from the road clearing.
Honestly it’s probably a wash, but I wish there was snow removal funding.

It only adds to the sense that he was quivering with barely restrained rage as he wrote the order, which also came through in the text quite nicely I thought.
