It would be one heck of a pedestrian hazard. Anybody foolish enough to touch those parts of the car while walking by would burn themselves - even after the car sat for a while. Moving the radiator to the outer skin also makes any fender bender a much more serious event. Radiator fins projecting from the car would be dangerous. Its bad enough for a pedestrian who is grazed by a passing car without having to worry about being slashed by blazing hot radiator fins!
