You are an engineer and base your conclusion on your own observation only - come on I expect more from youThat is because people don't actually buy Ferraris to drive, they are only for being seen in. I don't think I have ever seen one on a road that would be fun to drive, just sitting in traffic in fancy urban areas or prominently parked in front of a fancy hotel or restaurant by the valet.
That said I am sure a lot a purchased for the fancy people out there and never see any real use but there are also a lot who put them to good use in Euro land. Just drive in Germany you will if you pay attention see plenty people using their fast cars.
