It certainly does sacrifice utility, efficiency and (especially) affordability, but so what? It's still a masterpiece of engineering. There's room in the world for both types of products: the ones that do all things reasonably and the ones that do one thing extremely well. The one-thing-extremely-well type are usually the more interesting, whether they be designed for ultra-high speed (Veyron), ultra-high efficiency (Tesla) or ultra-high affordability (Nano).
