It seemed in the past that we all had to learn about bad weather vfr flying by pushing on too far before turning back. Some of course bumped into sticky out things like hills. Probably nowadays there is more focus on getting onto the instruments early, but many didn't have any back then (even a radio!). I've always thought that there should have been more focus, perhaps there is nowadays but flight into terrain has always been a killer. Knowing how soon to turn back for a tyro pilot is better taught than learned from experience.
