In the 60/70's when I was a rocker I always carried mine as we were flagged down on a regular basis by foot plod.
One night when I was flagged down it was raining and plod said - Got ya license mate - No I said thinking I ain't getting it wet and I heard him curse under his breath- Out came his note book and he wrote down all my details - gave me the slip to show it and said on your way -
On my way was 50yrds down road to cop shop - so handed form over and desk jockey said this has just been issued - Yep.
It seems not showing your license was a hassle for plod so I have never carried it since - They stop me they can fill in all the forms.
