Of course, they do serve a purpose, in that there's more often than not airbags in them, plus they provide structural integrity often lacking in older cars - so making the car safer for its occupants at the cost of anyone outside the car.

Say, I have a Range Rover Classic (1972, 3.5l V8) I mostly use for fun and games during weekends in the summer months. Its A-pillars look like strands of spaghetti, making for excellent situational awareness from the driver's seat. It is effectively like driving around in a moving greenhouse. (Doubly so in summer, seeing as the A/C is of dubious efficacy, to put it mildly.)

If I ever roll the thing, I'll be done for, though.
