Traffic was snarled in the Mission District on Thursday evening, after a recklessly driven stolen car crashed and injured two people.

According to San Francisco Police Department spokesperson Officer Gordon Shyy, at about 7 p.m. Thursday night, the driver of a stolen car jammed on past the stop sign at 18th and Bryant Streets, then collided with another car and two parked vehicles.

Shyy still isn't sure why the stolen car was being piloted in such a dangerous fashion through SF streets as, he says, police weren't chasing the vehicle, and its questionable origins were only discovered following the crash.

The driver of the stolen car sustained life-threatening injuries, and a passenger in the stolen car was less seriously harmed. Both were transported to San Francisco General Hospital. Luckily, the driver of the car they crashed into "did not sustain any serious injuries," Shyy says.
