Lately, I always noticed that my brother will ask someone to answer or read his messages on his phone while he was driving. He already got that habit because I was once told him not to text nor answer the phone when he is on the road for it is very dangerous. Driving + Texting = Accident most of the times for your attention will be divided on keeping alert on the road and clicking all those letters on your phone.
My sis NEVER answers her phone while she was driving especially when her kids are with her and I commend her for doing that. She'll never put her family at risk just for the sake of answering the phone. Almost everyone already knows that when she can't answer the phone it is probably because she is driving.
Not everyone follow the "no texting while driving" habit though like you can see in this video. tsk tsk..
