Since most women view being approached by a guy as some kind of insult/assault, small wonder guys cease bothering.
I recall seeing a young woman broke down on the side of the road one time and I did what anyone ought to do and stopped to make sure she was OK...
She gave me this look like she was about to pepper spray me, and a caustic attitude to go with it. I got back in my car without a word and left her there.
I don't stop anymore.
Because, you know, there is obviously something wrong with me.
