I agree but however Miami already has decent transit for the city itself. It isn't comprehensive by any means but it's enough to make leaving your car at the local train station and commuting in viable for a lot of people. What is missing in the area however are fast, cheap intercity links (until now) and more importantly fast, reliable commuter rail. Brightline (and hopefully soon to follow Tri-rail) rolling out fast, regular commuter rail to the lower third of the Florida peninsula would mean that south Florida would have rail transit viability (and range) comparable to the NYC metro area (which is probably the best "no car" metro in the US at the moment).
