A lesson is not learnt until a change (in this case, the rider checking they are carrying essential items) is made. Till then it's a 'lesson identified'.
Drove past (then stopped and went back), a guy yesterday who was sitting by the road, bike on the ground. He had had a puncture, had replaced the tube, only to find that one 'failed'. I didn't have my bike with me so could not solve that and "his missus was coming out to pick [him] up" so he refused my offer of a lift.
Add patches to his check list, perhaps.
