I use this neat thing that everyone has on a smartphone these days but... for some strange reason... nobody uses. It's speech-to-text, and all modern smartphones do it. I talk what I want to say and the program types out what I said.
If I had to actually type out what I say I'd never text while driving. But since I can just talk what I want to say, texting while driving is easy.
Of course I'm in west TN. If I lived in a city with a lot of traffic, even talk-texting would be out of the question.
