That's OK. The Dutch have figured out that their commuting bikes are for cycling on the road, not in the canals, and their bikes also have brakes that work in all weather, so the lack of "safety" railings causes no "safety" hardship. My experience the "safety" railing are on the bridges over the canals; along the canals there is less immediate proximity of pedestrian/cyclist traffic. There are small barriers often to keep cars park.

Note how useful a Smart car is for parking in tight spaces; also notice the "safety" railing protecting the tree.

Attached other Amsterdam pictures; note pedestrians and trams and trolley tracks. Somehow practical people can figure out that cycling is possible amongst all of it without making a BFD race out of it or going into a tizzy about weight-weenie-efficiency or "safety".
