I've had the yelling from cars, but no more when running than when doing anything else on my own. One time they just yelled the word "TITS" out of the car window as they rolled past. Observant of them, I suppose, and actually understandable at least, unlike those times you get a garbled, doppler-shifted sentence trailing off into inaudibility as they zoom past. Seems to have tailed off now I'm late thirties, though.
I think that men who don't do this often have no idea just how often it can happen (to some women, in some areas, at some times of day, etc.) — the hecklers tend not to do it to women who've got a man with them, so decent blokes don't really see it. DP has always been both baffled and furious any time I've mentioned blokes yelling stuff at me. Once, he was waiting in line at the chippy and I was hanging around outside vaping, probably as it was pretty packed in there. Got yelled at incomprehensibly from a car, so ducked back in to see if he'd finished, mentioned the vehicular troglodytes, and suddenly a whole chip shop queue full of men were outraged and seemingly ready to storm out there on my behalf. I think it's a small proportion of blokes that get it into their heads to shout stuff at women they don't know, and probably only at a certain stage in their lives, and the rest recognise that it's not on.
Edit: I've no idea what ethnicity or "cultural" background is arsehole a culture? most of them were, but whenever I've seen their faces, it's just been men who look much like any other local men. So in most places I've lived, that would be mostly white.
