heres another question thats bother me privately for years, the ‘skid marks’ on the slippery road sign don’t and never have made sense?
You understand what the sign means, probably immediately, so it makes perfect sense: the crossing of the tyre marks describes a skid/spin/slipperiness, whereas two parallel wavy lines would be ambiguous and easily misinterpreted. If you’re splitting hairs, then how about the fact that there’s nobody* driving?
