Michigan roads seriously suck. You can actually feel the difference when you leave the state and enter Ohio.
Ohio drivers, for some reason, seem compelled to pass you on the right of the highway, even when the left lane is clear and available for passing. Why this is, no one knows.
Ohio is also a helluva long state, and just as you think you've made it, the area in Cincinnati right before the bridge between Cincinnati and Covington, Kentucky is always under construction, always having a goofy traffic jam and the signage basically sucks. Again, no reason why, it just is, Every. Single. Time.
Tennessee drivers tend to be fine, although just as in the above states, BMW drivers have not ponied up for the expensive turn signal option for their vehicles.
Georgia - Atlanta traffic on 75 really sucks, and Atlanta goes on forever. Not having the express lane open was a BS move there Atlanta, really. The traffic just past Atlanta near the 475 Valdosta bypass somehow manages to suck even more and go even slower. But at least there are good BBQ stops close to the highway which makes up for it somewhat.
Florida drivers are their own special breed:
Yep, lots of left lane hogs at or below the limit, with lots of people in all lanes that couldn't find a speed limit with both hands. Those people were coupled with those who thought the speed limit should be ignored and weave in between those who don't doing about 95. Watched one moron do 10 lane changes going across all lanes no less, in less than 3 miles, complete with tailgating before each lane change, and it didn't actually get him all that farther than if he just stayed in a lane.
The most important question with Florida drivers is: Can someone please tell me how the living hell you can manage to be useless enough cause an accident on a clear day, with perfectly smooth and dry roads, with said accident being big enough to shut down the entire freeway going south to a complete halt for over an hour and a half?
That was no fun parked sitting in that and finally seeing 4 tow trucks come up from behind us and then go on up to the accident location and it finally began to open up after that. Sheesh.
One possible answer could have been drivers like the one idiot I saw texting with both hands, while speeding on the highway and doing a fair bit of weaving, because hey, who needs to touch a steering wheel when going 80-85 mph, texting is more important, right?
It was an adventure getting to Florida last week, and that was without any particularly bad weather aside from a dash of rain in spots.
