Here is a different take:

Most cyclists fit nicely inside 44cm wide bars.  44cm is only about 17 
inches,  If you assume that the cyclist is 1.5 feet wide and are riding with their 
left shoulder near the line, that leaves 3.25feet  from the TIRE to the edge of 
the road.  

Certainly that is plenty for someone who is carefully riding at 25mph or 
more, paying attention to what is ahead, etc.

I find it ironic that you would find having two feet to your right a concern 
when in the past you have stated that you are comfortable riding in a close 
pace line which means you are following someone more closely than 2 feet.  At 
25mph in a paceline 2 feet is about 1/20th of a second, well beyond the reaction 
time of even the fast human, so one is a sitting duck.
