When you carry a block of wood to place under your sidestand when you park.
When you park your bike closest to moving traffic in a parking spot so it won’t be obscured my parked vehicles next to you.
When you know to face your bike uphill before you have to make a K-turn, to let gravity assist in reversing your bike.
When you act as reflex to look for ways to avoid impact rather than grabbing a handful of brakes.
