What are your biggest issues when driving the one lane, neighborhood streets of Miami?

When driving in Miami on the backroads, neighborhood streets, side streets, one lane streets, whatever you want to call them. what is the biggest problems you come across. So far, for me it's the grown adults and high schoolers who throw a fit when everyone else isn't driving 20+ mph over the speed limit. We don't care if you are in a hurry or have poor time management, don't tailgate people trying to just get through the day.
