Cute, but I disagree with the sentiment. Modern cars are chock-full of special-purpose fasteners, optimized for machine insertion, minimum parts count (when was the last time you saw a lockwasher on a modern car?), etc.
I've got some bolts from a 80 Chevy, that are not only pointed, but the threads extend down the point, plus they have 3 lobes to the threads! (Serves to lock the bolt.) The hex head also includes a "washer" portion so no flat washer needed even though they go through a slotted piece of metal.
There is just no way you could ever find another bolt that looks the same as that!
Oh yeah, and they went into captive nuts that were shaped to match the inside of the complex shape frame tube then welded in place. Other places on the car, the threads are simply formed as part of the panel.
