Dozens of cars sped across San Francisco early Sunday, putting on sideshows in several neighborhoods as spectators packed the streets in the middle of the night.

San Francisco police got a tip late Saturday that several cars were driving into the city for a sideshow, officials said.

The group met near the former site of Candlestick Park at about 12:30 a.m. Sunday and proceeded across the city, hosting sideshows in the areas of 23rd and Dolores streets, Geary Boulevard and 30th Avenue, Market and Clayton streets, and Loomis Street and Barneveld Avenue, police said. There were reports of sideshows in other parts of the city as well.

Each show drew 50 to 100 vehicles. There were no reported citations, arrests, injuries or collisions, police said.

Officers documented the sideshows with body-worn cameras.

“This type of activity presents a danger to the community, first responders, spectators and participants,” police said in a statement Sunday. “We will be working to determine the identity of the persons and vehicles participating in the sideshows and will use all available legal resources to prosecute those involved.”

Police said the sideshows are still under investigation and declined to comment further Sunday.

Kate, 49, who lives in the Richmond District, said the sideshow in her area “went on a really long time” and residents called police. Officers on scene just stood and watched, she said.

“What’s disturbing to me is that they didn’t intervene,” said Kate, who declined to give her last name out of privacy concerns. “It was very loud, and I don’t understand why they didn’t just stop it.”

San Francisco police declined to comment Sunday on whether officers normally disperse sideshows.
