I was behind this truck yesterday on my way home from work. The truck had lots of long, metal rods on the top. Apparently, they do sidewalks and such, and the rods are used to brace the cement.
But the rods were unsecured. They had NOTHING holding them down. All I could think of was some kind of Final Destination death where all of the rods flew off the the truck, smashed through my front windshield, killing me instantly by piercing my heart and lungs.
Needless to say, I passed the guy quickly and distanced myself.
