Indeed. Many of the two lane rural roads out here have no shoulder, so negotiating traffic might be less than 3 feet side to side clearance, with impassable ditches/dropoffs/obstructions at the edge of the pavement. In those instances, a motorcycle should be able to find clearance unless the lanes become completely obstructed as with a car crash or some such. No means of transport is going to be a sure thing, so it helps to have alternatives.

How about a pickup towing a trailer with two bikes on it? Then if traffic plugs up too much, at least you have a high speed alternative. If it gets too snarled, then foot traffic is almost always a final option.
