BurrMan,
If Aventador had such sharp edges like on this concept you would have cut your hands if you decide to wash this car...

Aventador and practically all cars never has such sharp edges, they all more all less smooth with fillet or other technic.
That abstract sharp edges even do not produce any reflected light(spots) if you look carefully on Aventador you will see thin spots on edges and it because they are filleted or so ether, check picture.


That sharp edges for me personally are artifacts of not polished 3D models. In real world we can meet such sharp edges only in specific products life knifes etc... or on unfinished products like cuted metal.
