I think that we need more sense of humour on the road
Many of us had experienced aggression on roads. Sadly, there are lots of angry drivers. They are aggressive as well as dangerous. Such situation might ruin the whole trip. Nonetheless, it is not just uncool. It is also absolutely dangerous. If you are aggressive, you can’t stay focused on driving as much as you should. Angry drivers are more probable to behave risky on the road, while trying to tease other driver with such behaviour as starting to race or avoiding being overtaken.
