Frankly, you're not going to have much success opening ANY car door if you're on the roof. This is because the roofline will deform, and the door will either become jammed in place, or the friction with the ground will be too great to overcome. I've got a firefighter cousin, and I asked him about it, and he said he'd never seen a rollover where ANY of the doors opened successfully, including his own rollover. Usually the windows broke out and provided enough room for escape. Chances are, the driver was unconscious, or just couldn't escape the restraints (a risk with any vehicle).
