And if someone is in the left lane looking to do 11 or more mph above the speed limit, it is your responsibility to move over and just let them.

If you 're not able to handle that responsibility, that's fine. Just stay out of the left lane. You're not built for it. Unless you're a cop, you're not the arbiter of how fast everyone else can go. You should be treating any vehicle behind you in the left lane like an ambulance. Move over and get out of the way.
