A sheriff's deputy really had to put the pedal to the metal to keep up with a suspect who was speeding well over 100 miles an hour. The Culpeper County Sheriff's Office in Virginia said a man was pulled over for speeding on a highway, allegedly going 78 mph in a 55 mph zone. When the deputy ordered the man out of the car, authorities say he took off in the vehicle. The deputy's dashcam caught the ensuing chase.
