About ten years ago, I was driving on I-70 and was about to exit, when a got behind a truck which had brick pallets on the back. On the exit, one of the pallet snapped, and the bricks started to fall all-over, hitting my car and damaging two wheels on passenger side.
The worst slow drive? Route 1 from Miami to Key West. I was driving with my mom and somewhere in Key Largo a car cut infront of me and drove waayyyy below the speed limit. After 30 min we pulled into some of the islands and enjoyed a picnic. Any way, I was able to caught up with the driver :)). Another bad drive is a route 6 in Cape Code to Provincetown. If you get behind the camper, it is impossible to pass in miles on single-lane road.
