When we were doing 'Freaks and Geeks' I didn't quite understand how movies and TV worked and I would improvise even if the camera wasn't on me. I thought I was helping the other actors by keeping them on their toes but nobody appreciated it when I would trip them up. So I was improvising a little bit back then but not in a productive way.
People have to make journeys what we want is people to have alternatives in public transport so that they can make a choice about the sort of way in which they're going to travel.
