I could prove this point with a photograph taken whilst walking on a Welsh mountain 2 years ago. I met four teenagers at the top - two boys and two girls.
I was fully kitted out in waterproof gear and carried a map, hiking GPS, food, two flasks of hot drinks etc. Of the teenagers, one girl was in torn jeans (modern fashion type) and the other in a tight miniskirt and slippers. They looked the part but were not dressed for even moderate hill walking. Imagine if the weather had turned, which it can easily do on a mountain.
I did take a photograph with a telephoto lens when they were a sufficient distance away to show my teenagers how not to dress for a hill walk but will not post it up in order not to incriminate myself. The photograph was taken purely for educational purposes, Me Lord.
I would most certainly categorise driving 80 or 100 miles after a storm with live advice to avoid travel as being irresponsible. Unless of course it is to Barnard Castle to check eyesight during travel restrictions.
