One of our 18-wheelers had a tire come off. A man jumped out and tried to stop it. Of course, the tire flattened him. Our CEO said we should offer the guy a free lobotomy.
I remember an incident on I-5 near Seattle back in the early 90’s when a semi lost a wheel. There is a section of the highway with a pretty decent grade that runs straight as an arrow for about three miles.
The wheel rolled all the way from top to bottom, rolling against the flow of traffic and reaching speeds around 50 mph, all while traffic swerved and dodged the damned thing.
As I recall it finally crashed into some vehicles, but only after losing most of its velocity by rubbing and careening off of guardrails.
Scary stuff.
