I tend to drive on 95 north, in Brickell, Downtown, Little Havana, on the 395 and 112, Miami Beach, north Miami (up to 100th), and to the airport. If it can handle these places it seems like it's something to consider.
For the most part it works fine in Brickell and downtown. I put a link to a street view of one tricky intersection above. It also struggles here when you're trying to go south on Miami Ave:https://www.google.com/maps/@25.7626232,-80.1929899,3a,75y,2... basically where the black car is going south it needs to follow the street in a 90deg curve to the right then immediate left at the stop sign. Sometimes it tries to just go straight there, i.e. to where the truck is.
Also, i do often need to "intervene" by pressing the accelerator since the car is a bit to passive for the typical lunatic miami drivers.
