There seems to be so much hate against bikes in this thread.
I see the problem of parking inefficiently on the sidewalk as in the picture, but it really is such a small problem. Just move the outer bike 2 meters and everyone is fine?
Thankfully there are some more reasonable commenters as well but the majority seems to suggest knocking the bikes down or similar.
It just makes me sad to see people complain this much over such a small thing just because they are bikes. I love bikes and could easily have been that guy who parked beside my friend to just pop in and get some snacks or whatever.
Bike parking capacity is woefully inadequate in the Netherlands, at least in the Randstad.
