He describes himself as a human crash test dummy.
Every two years, David Thome, 60, of Hastings maneuvers a pair of vehicles into other cars to cause collisions.
He drives the bullet car into a target car for the technical course of accident reconstruction training at the Law Enforcement Training Center in Grand Island.
Thome, the highway safety grant coordinator, said the speed for each crash is kept low enough to prevent internal injuries that could be caused by the momentum of the vehicle.
"We don't pick a number out of the air," he said. "We do calculations prior to each crash. I don't have any death wishes."
