Arnold Schwarzenegger was just involved in a bad car accident so bad his monster SUV rolled over on top of another car, and that driver was badly injured. Arnold was driving a Yukon SUV when it collided with a red Prius at around 5:00 PM PT. His SUV started to roll and ended up on top of the Prius, then continued rolling to the left into a Porsche Taycan. One eyewitness says it was crazy it looked like a stunt in a movie. The collision was intense enough that the airbags deployed on the Yukon. The woman who was driving the Prius was injured bleeding heavily from her head. We're told an ambulance took her to the hospital. Arnold, we're told, is OK and is deeply concerned about the injured woman. Arnold wants to personally check up on her.
