It's interesting he chose to do that.
Ghosn was big on Renault's Formula 1 car racing team (head of Renault), and it's occurred to me a number of times that each of these F1 teams packs all of their stuff into gargantuan road cases, and then the Formula-1 infrastructure for the "show" - enough to fill 6
chartered jumbo planes, sometimes 7. Plus cargo shipping.
From a smuggling standpoint, it presents a unique opportunity I think. They go literally everywhere to race: Russia, Azerbaijan, Turkey, U.S., Abu Dhabi, China - 2,000 tons of road cases.
....and with thousands of people, and with some... sketchy oligarchs involved. Oil magnates, Russian mining oligarchs, Italian "businessmen", etc.. Ghosn being a sketcher himself. I would be highly surprised if smuggling isn't tied into Formula 1 transport
at some point. Weapons, nuclear material, whatever.
Ghosn thinks to hide in a case? "Hmmm...."
