We try to drive in ways that provide the least aggravation to other road users. We are generally going less than highway speed and will ease to the right when safe - occasionally we have signaled and gently applied the
brakes and pull further off the road.
My pet peeve is an entire caravan of huge trailers travelling SLOWLY together. We can't see past to overtake, they apparently NEVER look in their rearview mirrors and pull over a bit. If we manage to safely overtake one there are maybe ten more ahead and now we're caught between two big rigs!
