So why isn't your entire car molded like a plastic model? Well the titanium itself, as mentioned above, is still very expensive in its base state. Amorphous alloys, because of their relative newness and current rarity, are still expensive. But if more guys like me keep telling the average consumer how important things like this are, car manufacturers may start looking at ways to bring costs down. So the next time you get a chance, take a look underneath your car and try and appreciate what's there. You might be surprised at just how pretty it is.
