Anyone read JC's review of the Veyron in the times?
Not only the fact that he rants and raves about how good the car is but also tells you something about its development.
Like how the original body shape wasn't areodynamic enough for 250mph and would only get it to 235mph. So first thing they did was make the wing mirrors smaller.
This only meant that the cars nose wanted to lift up at 200mph, so they had to put them back on. The wing mirrors were generating so much downforce they kept the damn thing on the road!!!!!
Things like that make you realise how much of a engineering accomplishment that car is!
