Some drivers are known to be extremely rude on the road. That's not the case in Japan, where drivers have developed a cute way of saying "thank you" to each other. 

When drivers wish to show their appreciation for others, they simply tap their hazard lights. This lets the other drivers know they are thankful for helping them out. I'm sure this makes driving a much more pleasant experience, and I wish more people did this everywhere. Don't you agree? Let us know in the comments below.
