I primarily stay towards the left so I'm better seen behind the car in front of me and so they're more aware of my presence as well!
This! I almost always ride on the left. When I do this, I notice oncoming traffic will damn near drive on the shoulder! I've also been known to drive in the left passing lane on a 4-lane split highway at dawn and dusk to have better reaction time to whatever might come out of the ditch to the right.Left due to Moose and deer. Keeps me centered in the road and more time to react to those wanting to cross the road.
