It depends. If you are wearing a seatbelt and your car gets jammed in between something and goes up in flames, and the seatbelt gets stuck, then you can't get out. You might be in a little bit of a situation.
But at the same time, if you roll over or something like that, then the seatbelt can save you from tossing around inside or possibly outside the car.

From helping my father with the tow trucking business, and other tow truck drivers themselves, can tell you that they have seen both sides of this questions numerous times.
