The only menace and dismal failure is Bambu.
I walked thru the streets of Tehran yesterday (Youtube).
No traffic lanes on the roads, vehicles just do their best.
Went into a mall, 3 levels, shops had latest baggy pants, T shirts and baseball caps for men. Sneakers of all types, jewellery stores...other assorted stores 'as usual'.
Hard to walk on sidewalks, merchants cluttering up the space.
Littering is obviously not frowned upon.
Large billboards of the Ayatollah everywhere.
I wouldn't be rushing to live there...if I were looking for somewhere.
