I've never spent any significant time in Miami outside of airport layovers, but I wonder if most locals there actually do walk over to strangers and start speaking to them in Spanish first, since as a tourist, a very obvious clue towards the relative balance between French and English is the way locals in Montreal speak to someone in French first, and then switch to English once they sense any sign of hesitation.
