Actually, I find that almost everyone on the sidewalks here (cyclist or otherwise) are distracted by texting/radio/etc. In fact, back when I used to bike exclusively on sidewalks, they were the biggest problem of all. It was an iPod-listing pedestrian that lead to me crashing and doing an endo one morning on the way to work, which was the final nail in the coffin for sidewalks for me.

Simply, peds are just as distracted and unresponsive...sometimes even more so.
