Engine start button of Bugatti as always is on the steering wheel, the interior of this car is like spaceship! I am serious, they put all of their effort to make it look like spaceship and in my point of view it is so cool. Do not forget that, they put lihgt between driver and passenger (actually I like this idea, this light made this car more alien looking than ever!). There are carbon fibers on the body and interior, when you buy car like this you should expect this kind of amazing stuffs too.
