It's still nuts and bolts, even the Bugatti Veyron. Sometimes technology doesn't always work as expected and this is only proven by the following video of a Bugatti Veyron with some engine failure in the middle on London. The car doesn't want to start and the traffic behind it starts getting irritated. Eventually the Veyron gets pushed off the road by helpful bystanders. This is not the first time that this particular Veyron has some issues, a little while ago the window wouldn't go up either!
