On Thursday, the driver of a Porsche 911 decided he'd take a shortcut around some construction cones and drove straight into wet concrete near Marina Green on Marina Blvd. in San Francisco.

"It was coned off," according to Bobswire, a user of the Paceline bike forums. "He was just trying to sneak in from a side street. [The] concrete looked solid." Bobswire reports that the hapless driver remained stuck in his car. "He didn't want to open the door and have concrete get in; the whole undercarriage and brakes will need to [be] cleaned or replaced."
