Which raises an interesting thought. Let's say someone rides to work every day without a bell. Say they are lucky enough to get five weeks' holiday a year, plus Christmas, and a couple of days off with a hangover or whatever. That's 45 weeks x 5 days, or 225 journeys into work a year. Suppose they perform the exact same flashy manoeuvre without a bell every morning, and come to absolutely no harm for four years in a row. Clearly then, they are an expert at not having to use a bell, and their judgement of what is safe is sound.
The thing is, would you fly in a plane without a bell, if that plane crashed and burned without warning on average every 901 journeys?
