Isnt left lane for overtaking usually? Just speed up a bit and merge to right.
And safe driving style (keep your distance) would save you from falling stuff much better than car that does 0-60 in 4 seconds.
Ok, fine, let me tune my example to be a bit more specific. You are not in the leftmost lane, you are in the middle one, but there is someone directly to the left of you, so you cannot safely swerve to the left.
