Why don't females look males in the eyes anymore on the streets walking?

They too digitally distracted with the iphone and facebook?

I can't know it.

I don't like to make eye contact with people I don't know because it can get awkward, especially someone walking down the street. That might encourage the guy to come up to me and say something and I'm really not down for that. I use my cell phone as a distraction and to look busy so I don't have any creep coming up to me.
