It was several hours after the accident, and medical examiners had already taken away the victim's body, but some gruesome evidence remained.

Behind the spot where the pedestrian came to rest after a driver hit him, his hat, a pair of headphones and one of his shoes sat on the roadway.

It was Sept. 3, and a few hours earlier, Eulogio Garcia Sanchez, 53, of Oxnard had been wearing them as he crossed the C Street at Elm Street in the pre-dawn dark, heading for a bus to go have coffee with friends.

When I zoomed in with my video camera, I could see the black hat had the word "cobra" written on it, and the black tennis shoe still had its laces tied. There was nothing gruesome about the items on their own, but there on the pavement, they were stark reminders of what cars can do to a human body.

Sanchez was by no means the first pedestrian knocked literally out of his shoes when a car hit him.

I can recall several recent accidents in Ventura County in which the same thing happened.

When Karey Marsh, 46, of Thousand Oaks,  was hit by an allegedly drunken driver while she was jogging near the edge of Oak Park last month, the impact threw her an estimated 30 feet into nearby shrubs but left her shoes behind, authorities said. In fact, emergency responders only knew a pedestrian had been hit because of those shoes.

And when an intoxicated driver slammed into an SUV on the side of the road and Officer Tony Pedeferri of the California Highway Patrol in December 2007, the impact launched Pedeferri 20 yards and threw him out of his boots. (The crash killed the driver of the SUV, who Pedeferri had pulled over.)

I first heard of someone being knocked out of his shoes when I was reporting on the crash that injured Officer Pedeferri.

When I first heard the detail, I thought to myself: I didn't know that could happen.

It seemed improbable, physically possible -- of course, objects at rest are inclined to stay at rest and all -- but incredible. Imagine the force necessary to throw a person so hard that a garment fastened to his or her body is pulled off by the impact alone.

It's something I would need a much better understanding physics than I have to really comprehend.

I asked a police contact and another from the medical examiner's office: Is this common? Neither common nor uncommon, they told me. It depends on a lot of things, but it does happen.

Most of us drive every day, some of us for hours, but how often do we consider that our cars are metal boxes weighing thousands of pounds, hurtling down the street at speeds that are mind boggling, especially when you compare it to the pedestrians, cyclists and others with whom we share the road.

Stay safe out there.
