Please do not imitate the action above when you're riding on your moving motorcycle. [Note that I said "moving"]
This is too dangerous and you might be losing arms and legs in the end. Please stop by somewhere safely, and make sure that the surrounding is alright for answering phone calls.
Just like the Punjabi guy in the picture.
You can make a difference.
So have you ever tried answering phone calls or replying message while driving at the same time?
