Anyone who has ever tried to avoid the white stripes of a zebra crossing can now say with certainty that it is of no use at all. There are no prizes to be won, no records to be broken and certainly no trophies to be collected for this challenge. The game, which many have played since childhood, remains a simple waste of time without any reward. However, for those who go one step further and manage to avoid not only the white, but also the black stripes, there may be reason for a moment of self-satisfaction. It is not necessarily an achievement that is celebrated on a world level, but you can certainly pat yourself on the back. Still, the same principle applies to this extra challenge: there is no prize. It remains a matter of personal triumph without external recognition.
