@ Bobby... Yes, I noticed these things you point out...  I also noticed how men wore suits.. drabby suits..  dark jacket and a pair of dark trousers... oh yea.. and a hat..  My father was a hat person.. ("hat people.." --what I called them).. No one wears them anymore.. as part of the dress code..

These dark drabby suits were worn regardless what job the individual was doing... Lol.. from digging a holes to contruction to driving busses...  Women on the other hand had more styles to wear.. You can see that on the film..

The traffic gives the impression of movement in an ant farm.. no official rules just curtacy instincts..  Great film.. I was impress with how much we as a nation have come a long..
