They have a few put more bike racks at the Vienna Middle Station and normal behavior has changed!
Originally they totally forgot or ignored bike parking and there were many problems with badly parked bikes. This creative freestyle bike parking was normal behavior.
Now it is normal behavior to lock your bike to the excellent Vienna Bike racks. Here is a very bad video to illustrate the current situation.
The capacity of bike parking is already nearly full so if the city want to encourage more people to cycle and to park their bike responsibly they will have to double the parking capacity again, otherwise they will end up with lots of behavior arguments etc...
