you couldn't be more wrong. Bugatti is perfect example. They have built the Veyron just to proof the engineering excellence. Not to make money! In fact, that project lost money but the result is pure delight. If you think that metric for innovation is money then I don't think we will continue this discussion in a constructive manner as you are blatantly ignorant to what innovation is.
Btw, the inventor of a wheel didn't make money, yet the innovation is still used!
For crying out loud, does everything has to be about money for you to even move a finger?
Actually, I think you couldn't be more wrong.
The invention of the wheel came out of a need to more easily and efficiently haul heavy loads and carry people. The empires with the technology prospered greatly from it (and captured lots of land too). So, yes, of course riches were involved in the invention of the wheel.
Bugatti (VW) as well as every other auto manufacturer routine make one-off concepts to develop and test technology for future mass-market models. It's part of the R&D budget, which is intended to reap dividends later down the product cycle, not in the concept model itself. The original Veyron concept was not build for kicks and giggles. It was a pure business decision. Sorry to bust your utopian ideals. Money makes the world go round, truly.
