Obviously the logic doesn’t work that way, but you absolutely do not see people showing up late to meetings and canceling plans last minute in Minneapolis or Boston the way they do in Los Angeles or Atlanta.
I live in Atlanta. People cancel their plans in Atlanta because they don't want to sit in traffic. (Or at least that's what they say - it's a good all-purpose excuse.) From what I know of LA it's probably the same way there.
Next question: why do Atlanta and Los Angeles have such horrible traffic?
