Option 2 physically walls off the Late Mergers in addition to mentally (in the minds of the Free Laners), making them easier to ignore.

I like option 1 because it forces everyone to move.

Yeah, option 2 would lead to someone hestitating/stopping in that lower lane. Then that whole lane is stopped because the front driver is too afraid to merge into moving traffic, and the moving traffic is going too fast to stop and let a lower lane driver in.
