In the lane.
Right where the passenger wheel of a vehicle should be.....and hope...and pray, they stay behind or do the right thing and pass in the other lane.
Where I ride, it is either two lane roads or single lane roads with little to no burm and what burm there is has cinders & glass ready to chew up a tire. If I try to ride the white line, the vehicles try to squeeze past me as oncomming traffic passes as well. By staying IN the lane, it forces them to wait to take the other lane & NOT squeeze past.
I've been in this area long enough that most of the local drivers know and we wave at each other as they pass (even though we have no idea who the other is).
On the other hand, there are still the rednecks that honk all the way past and wave with one finger as they yell "get off the &*#!@@% ROAD #$$$&%#!!
I dig deep and make no reply to these folks.
