In Dutch, the only (one) is “de enige”. People often use “de enigste”, which actually means the cutest. Enig -> enigste.
“Ik ben als enigste over” “Ja, schattig ben je zeker”
"“Ich bin der Einzigste, der noch übrig ist” “Ja, du bist wirklich süß”
“I’m the only one left.” “Yeah, cute you sure are”
In Europe (in my case the Netherlands, but it’s similar in surrounding countries) you cannot pass on the right and you can get fined for it. If you do pass on the right you’re taking a bigger risk because it is not expected.
You can also get fined for staying in the left or middle lane for too long. But that’s somewhat rare. You can get away with it a bit to pass an extra truck (our trucks speed limit is slower) or if the right lane is full and slower than the lane to the left of it, but don’t drive excessively slow on the left. Especially on the Autobahn.
