No, I'm saying that it's literally a survival skill to be able to understand men enough to be able to predict a stranger's behaviour. Is this unknown man in the train carriage with you likely to attack you now the other passengers have got off? (In which case relocating to a different carriage might be a good thing.) Are those youths the happy drunk types or the 'lets have some fun with this lone woman' types? (In which case the benefits of taking the long way home to avoid them outweigh the risks of taking longer to get home.) Is this drunk guy going to back down or is he going to glass me? This situation is getting hairy, is it time to back down myself in order to defuse it?
At work and at home, you can get to know individuals well enough to adjust your understanding of how they behave to take in their individual personalities. With strangers you don't have that degree of fine calibration.
A bit off-topic, but I think to some degree, women are (or at least were) taught the wrong survival techniques. There was a time when we had a lot of media attention focused on the idea of evil strangers who wanted to rape women, and barely any focused on rape by friends and acquaintances (which is vastly more common.) That's starting to change now, but we're still getting all sorts of weird messages I'm not sure are backed up (e.g. "Dressing slutty is asking for trouble", even though I've never even heard of a study of how clothing affects the likelihood of rape.) I'm not entirely sure these messages can be used to create or develop male characters without just furthering more misguided ideas.
(To be fair, I'm male, and I've never been in a situation where someone might suspect that I was going to get raped. However, I did once pick up a hitchhiker who was a tall, dreadlocked, informally dressed black man who turned out to be an ex-marijuana dealer. He was harmless, and I enjoyed his company.)
