You don't notice it when you are used to it.
Pre '75 there was nothing to control oxides of nitrogen, which smell pretty awful, and combustion was never clean enough back then to control volatiles and hydrocarbons. I think all they had were secondary air injection, which was prone to failure and subsequent removal
You may not remember the smell, but do you remember the color of the L.A. skyline?
