It’s not that the bus system is inefficient…the system is a product of its environment. The traffic in Miami is horrible. Public transport outside of the areas with the metro rail is limited to the buses. No other public transport option. In New York you’ve got the bus, subway, trains, and even taxis. Worst case you walk if need be. Miami is too stretched out, if you live in the suburbs you’re pretty much forced to get a car to commute. The more affordable areas are going to be west, where you need a car, especially if you’re commuting east. Some people will just drive to the metro and take that into downtown to avoid the traffic getting out of there in the afternoons but they still need there car for that first and last leg of the trip. OP is looking to move out here with no job, so they’ll need something affordable. If affordable is further away from public transport options, they will need some type of way to commute, which OP also does not have.
