Taxis!! Love them or hate them, they really push boundaries while using our roads daily. The fact that they are compensated by the amount of trips they do on a single day, brings out the creativity of each driver. By doing this, they tend to create short cuts to reach their destinations in the shortest possible time, with the consequence of endangering fellow road users.
However, if you think about it, on the one hand they bend the rules and test the patience of other road users to make a decent living, but on the other have there is someone in the taxi who appreciates every short-cut which assists in making it to work on time.
Have a look at this clip. This really pushes the boundaries of road safety.
