It was meant to roll

Another night on the drive to work...I-290 Westbound. I'm bumping The music so loud, I couldn't hear anything outside my SUV. Suddenly in the middle lanes, a flurry of activity as smoke and sparks envelope a mini van. It was like watching a silent movie.

My first thoughts: We're under attack, seek cover! (the government got me on that paranoid trip)

To my surprise, there was no panic. Traffic slowed to let the spark spraying van maneuver itself to a break-down lane. As I passed the smoking vehicle, the front driver's side tire was missing.

Continuing on, traffic reared to a halt; the missing tire was still rolling across four lanes of traffic, heading towards the grassy incline, where it picked up momentum and rolled back onto the expressway, causing another sudden stop. It wanted to keep doing what it was made to do, roll!

Devil Alert: Suppose, someone was to position himself on the incline with old tires and let them roll into traffic!
