(CBS/AP) "Car surfing" and "ghost riding" videos are littered across YouTube. Teens on top of cars, with no one behind the wheel and sometimes "skitching" - riding a skateboard pulled by a moving vehicle. These are a variety of terms for a wide range of dangerous and potentially deadly activities.
Police in Central Florida say that two teens were killed in a fiery crash that involved car surfing last week.
Two teens died when the driver, 18-year-old Joshua Ritter, lost control of the vehicle Tuesday morning. It rolled over and burst into flames.
Volusia County Sheriff's officials say the teen who was riding on the running board died at the scene. A second teen, who deputies believe was trying to get back inside the vehicle, died at Halifax Health Medical Center in Daytona Beach.
Two other passengers, 17-year old Ryan Jenkins and 18-year old Kenyanna Hawkins, were also hospitalized.
"An injury even at those slow speeds can result in significant neurologic disability and even death," neurologist Dr. Alan R. Cohen told CBS News' "The Evening News."
According to a CDC report between 1990 and 2008, 58 people died in car surfing accidents alone. Another 41 were injured.
Injuries and deaths from ghost riding and skitching have never been counted, so the numbers are likely far worse.
