Relearning Miami driving

I'm a Miami native (lived in Hialeah since I was 5). I'm moving back home to my folks place in Miami Gardens (in a week) to save and finish my Masters degree. For the past 4 years I've been living in a small town in the upper Midwest. I haven't driven on a highway nor driven past 25 mph (that's the speed limit here, you will get stopped for driving over 35) all throughout that time. I'm a nervous wreck about having to drive in Miami again (palmetto and I95 terrify me)and looking for some encouragement/advice on how I can adjust again😭 for the locals, please tell me shit has gotten better recently 😭😭
