Living in a less Catholic-heavy environment than Miami would be option #2
Would Socal girls insist on ambiguity? Girls in Vegas? Manhattan? Women in Houston or Scottsdale?
Perhaps, but less frequently imo.
I lived in San Diego for many years Billy P, grew up in Boston - i'm going to be honest I didn't notice much of a difference between the two (mia & san d. in terms of approach). All women largely do the same thing, it's hardwired into them. Yes, you can pick up on certain behavioral things here and there and sometimes the woman will be more forward (I know i've made posts on here with examples where the woman pretty much initiated) but there are also cases when you just have to say **** it and go for it. I don't necessarily fault guys for not being brazen enough to want to do it, but being 40 years old and having been in the game for quite a while now, i've come to realize sometimes you simply won't have a choice but to grab your balls and step over. If you see an ultra hot babe, the type you don't encounter often, you might as well take a shot. If your mentality is of someone that is willing to do whatever it takes and wants to win, rather than just watch from the sidelines, it will make sense. Some will say "But what if I get rejected?" Ok you got rejected, who cares, you'll forget it by tomorrow. At least you know you demonstrated courage and did something probably 90% of the other guys around you wished they had the balls to do. It is also not a reflection of your worth in any way, it's just one woman.
By not acting you are essentially rejecting yourself - you take yourself out of the game and then have to deal with the regret of not knowing one way or another. I know i've done that before, been a number of times years ago where I felt bad for not having tried to make a move with a particular woman. Would've preferred the rejection because then could've moved on faster.
