If they don't have the foresight to understand why texting while driving is dangerous, they should be behind of a car's wheel - but the rear wheel.

I text all the time, if you count Discord as a texting application, then that's it. As someone who live actively in quite an amount of servers, it's indeed not hard for me to see how texting can be dangerous sometimes.

Communication is two-way thing and it is certain for the receiver to have some response after getting the information (if this is not the case, reconsider your communication method, or go slap my business communication lecturer), and the response can be in many formats - they can be response in text, speech, facial expression, tone, small acts that reveal their state of mind, etc. Texting just transmits text, and nothing else, so the complete information cannot be transmitted perfectly. It just happens all the time when someone says that "it's a joke" but the next second they get a mute from the server moderator. Some voice will automatically read the text we see in our mind and it can be drastically different from what it was intended to sound like.

It is indeed very easy to misunderstand or stuff like that when texting, but sometimes it is helpful for me...like, the lecturer won't know that I am trying to hold my emotions when replying to her. Lmao.

Anyways, texting is already something tightly integrated into most people's life, so it's something that depends on how we look at it. I sure hate it when people don't know that they are being a dick, but most of the times we'll just live on with it :)
