For the most part, yes. But if you roll the window down and have the camera sticking out the window you won't be as protected.
The common myth is the tires insulate the car from the ground. This could not be further from the truth. If you think about it, the lightning has traveled thousands of feet to reach the car, it is absolutely nothing for it to ionize the 12-24" of air below the car to complete the pathway. What is going on is the car essentially becomes a Faraday cage, directing the current flow around the outside of the vehicle away from the occupants.
