I didnt say he was drinking and driving nor was it on Shabbos
I said he was engaged in reckless teenage behavior, Drinking is an example of reckless teenage behavior. Driving fast with a girl in the backseat is another example of reckless teenage behavior (as in this story). I am led to belive that its mostly teens who are texting on Shabbos.
I would think that Drinking occurs more often than reckless driving, but I could be wrong.
My point is teenagers enagage in reckless behaviors and its difficult to fight them all. You sometimes need to pick and choose which ones to fight.
