A drug or drunk drivers reaction time is better than a texting driver. While drunk at least you are looking at the road. Someone texting has no idea what is going on around them. That is going to slow down your reaction time a lot.Drivers who use their mobile phones to send text messages while behind the wheel have slower reaction times than those who have been drinking or taking drugs.

I think there should be tougher penalties for texting while driving. Talking is bad enough but I imagine texting is worse. I think if you kill someone in a car crash because you were texting then it should be treated the same as it would if it were a drunk driver.
