I do go out in the dark, but not unconditionally.
I'll walk home from a night out if I'm with my friend who lives nearby - only a two minute walk away from me, on a lit 24/7 main road.
I'll walk by myself in the dark in the late afternoon/early evening. Probably not after 8pm. My route home from work goes through a rough bit of town and the atmosphere changes totally after 7pm, which is my preferred cut off time.
Ideally, my preferred choice of in the dark transport is a bike: no drink drive limit; no risk of a creepy cab driver; very very limited risk of being followed home; easy to speed up without making it clear you're running scared; can usually park it within 50 yards of wherever you're going, so no back to the car risk; you're a moving target for anyone looking for trouble, and ultimately with these things you just need to be more difficult to attack than another person would be. The only difficulty is time taken to get my bike unlocked - I've had some unpleasant experiences during those 30s-1min. If I'm out with any men, or a group of girls going off together I ask them to wait for that part.
Maybe it is overkill. But I've been cat called walking down the street in leggings, dress and s kagoule. I've been groped in bars. And I've had men proposition me. The likelihood of anything actually terrible happening while I walk home is very low. The likelihood of something moderately annoying and grim happening that leaves me spending the entire walk in a state of paranoia is pretty high. So my precautions seen reasonable to me.
