A great proposition and the P11 prototype works well, so we think. But the only way to truly test the concept and the product is to show 'the man in the street'. I hit the streets of London and ask people directly. Stopping busy Londoners is not a walk in the park, but outside St Paul's Cathedral holding up my sign, I wait for engagement. People's feedback is consistently positive, some of it exuberant. Messages about price are taken on board, but we come through the street jury with a clear endorsement. We are on course.
