No, you are not. You shouldn't suddenly move to a lane left of you without checking that there is no faster traffic oncoming though. And you might move right, if possible. But it is not a special danger.
I'm not sure why you are getting downvoted, this is absolutely true on even just a semi-active Autobahn.
Feels like people are actively out for you at that point, you'll have close-calls and will get nearly rear-ended by some Audi that wants to switch lanes where it shouldn't in no time.
