View attachment 170837 Fessenheim is 620 km from Tilburg. (As you can see it takes 34 hours by bike
)
Good central EU location and as Musk has remarked Alsace/Elsas-Lothringen is basically as close to Germany you can get while still in France. (Fessenheim doesn't strike me as primarily a French sounding place).
Look at how Musk masterfully played states vs. states with the GF. He is going to do the same with EU countries. France, Germany primarily, maybe the Netherlands will get in the bidding. Outliers are Slovenia (discussed previously), maybe Slovakia. Less so the Chezch republic (Skoda would mind).
Factory in EU announced in 2016, the odds are very good.
