Did you know that almost every city believes this about their local drivers? I've gotten it in LA, Boston, NYC, DC, SF, Philly, Atlanta, and Austin. Adding Miami to the list.
Not to mention The Ticket Clinic, a private service to pay a small fee to get out of traffic court. I probably had 10 different traffic violations thrown out, for $80 a pop, when I grew up there in the 00's.
I currently live in Miami. I've lived all over the country. I'm from NYC burbs. I thought NYC drivers sucked before I moved here almost a decade ago.
Miami's drivers are horrible, mostly because most of the people here have never been trained to actually drive.
This is exacerbated by the dysfunctional government which is happy to let developers do whatever they want without regard to impact on traffic flow, while doing no investment in infrastructure itself. I'm generally pro-growth, and I think California goes too far with its restrictions, but living in Miami has caused me to gain some appreciation for the reason behind some of what California does.
My experience with Florida driving was not a great experience for the few years I lived there.
