If you want to expand your mind, travel to south east Asia or India for a bit and see a different way of how billions of people live and drive every day.

Yep. I cannot speak for India but I lived in China for a few years. Honking is useless there as well.

It is used a lot, but without actual benefit IMHO.

Edit: perhaps less useless since drivers tend not to look before changing lane. That's another issue.
