I have a love-hate relationship with those bollards. In some places they are a necessary evil. But, I also do some riding with a cargo trailer, and in some places I have only inches of clearance to spare. The things are terrifying.
I do think communities should be very judicial about the use of those bollards and put them in only where absolutely critical.
Put them in well lit areas, and with lots of bright paint both on the posts as well as on the pavement approaching them.

I thought there was a photo, but I can't find it. Anyway, if this is the one I remember, it was on a quiet trail, with a dark colored post in an intermittent shade area. And the post wasn't right near a driveway where it might be expected, but was some distance along the path.
Of course, if cyclists can't see the bollards, I'm not sure how one would expect wrong-way drivers to see them.
