If you're like me, you're thinking, "Okay, is it 75, 94, or 96?". Having driven on all three of them on the east side of Michigan, where speed limits are treated more as a minimum recommended speed, I assumed it had to be one of those three. It wasn't. It's not an interstate, but a US highway.

Unsurprisingly, as the state—and clueless drivers—go hand-in-hand, Florida's U.S. Highway 1 is the most dangerous in America. This stretch of highway runs from Key West into Georgia along the state's east coast and sees an annual average of 108 fatalities.
