Texting while Driving?

Every where I go anymore, I see some dumb*ss behind the wheel sending text messages. It makes me so sick to see because they are swerving all over the road just like they're drunk. I saw a study that said driving and texting is just as dangerous as drunk driving if not more, yet in most states it's still legal. I think it should be illegal, but not just a fine. People texting and driving should be arrested. I know this may sound extreme, but if it's just as dangerous as drunk driving, then why not the same punishment?
