Texting while driving (or other similar distractions) results in slower reaction times for drivers than even drunk drivers. Yet it doesn't carry the same stigma. I would even guess a big portion of the people who have absolute disdain for drunk driving are guilty of distracted driving from time to time.

I don't know what the answer to that is, since it's more difficult to catch and prove But at the least we should all call out our friends or family if we see them doing it, the same way we would if they were about to drive while drunk.
