Hey Yupette,
I just returned from once-beautiful Amsterdam, which has been overwhelmed by bicycles. The Dutch state and local governments have spent a fortune on encouraging everyone to ride bicycles and funding bicycle infrastructure (like bicycle parking garages). Consequently, Amsterdam and other Dutch cities are a mess, bicycles, bicycles, bicycles. Oh, Dutch bicyclists generally don't wear helmets and obeying traffic signs is pretty casual. Stay tuned for a big bicycle mess in Arlington by 2020.
