I voted for “anywhere that makes the most sense.” Sometime there are serious dangers on the left (eg potholes) to be avoided. And my visibility is key. I agree with you that most motorists seem to think they own the entire road. It can be very intimidating to hold your ground when you have traffic honking and speeding past you. I wish before handing out driver’s licenses, each individual was required to spend at least 15 minutes on a bicycle in London traffic. Maybe then they would understand just how vulnerable we really are.
