The 17-year-old driver of a car from which another boy fell early Sunday could face felony charges in connection with an alleged "car surfing" accident.

An unidentified 17-year-old boy was critically injured after striking his head on the pavement of The Citadel mall parking lot in Colorado Springs.

Police said the two were taking turns standing on the hood of the car while the other drove in circles when the one fell.

He was in critical condition at last check in a Colorado Springs hospital.

Witnesses said several teens had gathered to watch the illegal stunt. 19-year-old Kelsie Simmons was among them, and says the victim had been standing on the roof of the car while another 17-year-old boy drove.

"It was really, really scary to see," said Simmons. "The driver made a sudden u-turn and the guy on the car screamed really loud and fell. I think he broke a couple bones... he's not doing too good."

Police say car surfing became popular in the 1980's. It was featured in movies like "Teen Wolf," and most recently in the movie "Grindhouse." Simmons says she's tried the so-called thrill ride herself.

"It's almost killed me a couple times," said Simmons.

Car surfing has already killed dozens of teenagers across the country including at least 4 from Colorado, over the last 3 years. Despite the statistics, Simmons says the surf is still up among her peers.

"It's just something teens decide to get up and do... it's not very safe at all."
