I'm pretty sure that Musk and most of the potential buyers are aware about this. But consider this - if Roadster has exact same road performance as Veyron (accel, max speed, cornering speed etc.) while being more streamlined that makes technically superior to Veyron. Imagine a concrete brick on wheels that has the same road performance as Veyron - its engine and aux controls should be insane and deserve an award on its own, but as a complete car it would less impressive as a Veyron despite being the same on the road.
