The California Highway Patrol is seeking more information about a "sideshow" on Interstate Highway 880 in Oakland on Saturday afternoon where participants were doing "doughnuts," a CHP sergeant said.
The CHP received a call around 4 p.m. about reckless driving on northbound I-880 at Coliseum Way, CHP Sgt. Diana McDermott said.
By the time officers responded, the drivers had left, however videos were posted online later that day.
The drivers fled after someone in one of the videos can be heard saying the police were coming.
McDermott said the trick driving on the freeway is "just not acceptable," stressing the dangers of driving like that.
"People think it's all fun and games until it turns disastrous," she said.
No one was injured in the incident, and the CHP is searching for those involved.
She said driving like this on the freeway is not common.
"I am absolutely hopeful this will not happen again," she said.
As to those who got out of cars and filmed the incident while driving, she advised exercising caution in the future.
Instead of becoming part of the dangerous driving behavior, she urged passersby to be "good witnesses" and share license plate numbers, vehicle and driver descriptions with the CHP.
"This has a definite effect on safety of others," she said.
Oakland is credited as being the birthplace of the sideshow. They became popular in the 1990s and have even found their way into music (see video below).
