Did you stop and move the shopping cart out of the way?
This is the Road Cycling forum. Road cyclists don't do that. They complain and leave that job to lesser folk.
I wear two hats. Sometimes the old ex-racer in training mode, sometimes as a responsible commuter who stops to clear branches and rocks. (On a hillside, treed commute used by hundreds I have noticed rocks and branches can stay for days. Silent comment on the local humanity.
