what a great question?? can you answer..............

Hi Kawalsukhi, nice question.I think it is because the person thinks he is the best driver. All others are idiots. They are not doing the right thing whatever they do Have a niceday

This is true only if one thinks the world revolves around them, and them alone. Many people think this way, therefore there are an overabundance of idiots and morons on the road. My suggestion to all, learn to be a very defensive driver, and hit the road with the idea that either no one can see you, or no one cares.
