Answer:
I'm not sure about worldwide, but in the USA, texting and driving can lead to:
1) Fines from the police officers, for it's now illegal.
2) You dangerously increase the risk of crashing into something or someone.
3) If you do crash, you'll end up either dead, seriously hurt (possibly handicapped), or your insurance rates will rise.
4) Most likely you'll lose your phone, too.
I can't name more.
