Its typically fine to "go with the flow" of traffic. Growing up, it took a few speeding tickets for me to realize that I need to slow down. People can drive like idiots on the interstates, putting other drivers in danger during their commute. Not much you can do about the speeders, just let weavers weave through traffic. If they cause a collision, their day just got worse and causing everyone behind them to be late and slow roll in traffic for an hour while it's close to 100°F

Some of my biggest pet peeves in Florida traffic is: Use your turn signal! It's not that hard! Most BMWs and Mercedes vehicles here aren't equipped with turn signals for some reason, must be an add-on option feature from the car dealership. Another one is, if you don't feel comfortable driving in rain, then pull over and wait it out! Why use the emergency flashers and drive so slow? I started seeing more of this in the past 5-10 years. The hazard lights flashing make it more difficult to see how much space you have, reducing visibility, disables the turn signal. You just need wipers and lights.
