Germany's *LARGEST* karting track?? (Kartarena Dinslaken)

Today i went to check out karting dinslaken which is probably the largest track i have ever seen, this video was recorded on the 1.5km version but on days when the full track is open the track can get up to 2.3km which is absolutely insane as times driven on the 2.3km track estimate to 2 minute+ laptimes
