I had the weirdest NSV yesterday I stood in the middle of the road at the bottom of a hill waiting to get across, (like you do ), cars kept streaming past and not stopping (like they do ), suddenly there was a huge roar of motorbikes, 50-60ish 3 abreast (all Harleys). They all stopped, waved me to cross the road, I crossed, turned round and waved my thanks and they all saluted me and beeped their horns. I giggled all the way to the shops.
