Of course I walk around in the dark, children need picking up from school/ activities for a start. I'm not driving less than a km (unless it's a rare occasion I have stuff that's too heavy or bulky to walk with)
My quiet suburb is well lit, and doesn't have people loitering around. There aren't lairy pubs to create hotspots. There's a flow of people going about business such as running/ dog walking until around 11pm.
If I lived somewhere remote where it was only unlit NSL roads or fields, that would be different, and my hazard concern would be traffic and tripping. As it is, I tend to swerve unlit woods/ fields mainly for the trip hazard, but that's not particularly limiting. Admittedly startled pheasants can be pretty freaky!
There are patches of town I'd avoid where people loiter around drunk or under drugs. I wouldn't hang around a red light district (although did functionally walk through some in my student days without bother) because the chances of encountering someone with malicious intent increases.
Most places are fine though. I'm a bit more selective about sticking to better lighting and avoiding places that are hemmed in, but there's not a substantial restriction on where I go between light and dark. I did C25k late at night because it was when I could do it around childcare/ baby's feeds. My health would be far worse if I didn't walk/ run at night.
DM was very much women shouldn't walk here or there or at that time. What she taught me was secrecy.
It's very depressing that on the rare occasions that a woman is subject to assault by a stranger, response is often "what was she doing there at that time". Why should she not be going about her lawful business? Why don't commentators ask "why was there a violent man loitering around there at that time? How can society reduce the prevalence of violent (misogenistic) men?"
Disproportionate fear of over-emphisised risks that curtails choices harms women. It's a barrier to physical activity (functional or intended exercise) and reduces social outlets. There are places where risk of potential harm outweighs benefits, but most spaces have more benefit than harm.
