The Industrial Engineers that designed the sub-assembly transportation process should be shot. It's quite possibly the most inefficent way to put an airplane together that I've ever seen. Way to use your manpower France.
If Air-bust didn't have Euro-PEON taxpayer money to waste and actually had to be a profitable business, they would streamline their manufacturing processes and build everything at the same site.
Politics, politics, politics. They have to spread the work around.
To be fair, US companies do a lot of the same ridiculous transportation processes. F-18 fuselages are built in California then shipped to Missouri for final assembly costing a fortune in shipping and insurance costs, all so that people in both states get jobs. But I certainly would hate to be living in one of those houses on the route when the parts come down the street at 2 am and miss your front facade by 3-6 inches. Good thing they probably won't sell that many. They're at 159 and counting, but I'd bet Kingfisher never takes delivery on their 5, and if Emirates didn't get essentially free gas, they'd be hard pressed to find uses for 43 of these beasts. They still need to sell about 100 more to just break even, and orders are dropping off.
