We live in an age where even when it’s your fault; you don’t want to be held accountable.  The issue is so pervasive that not only don’t you want to be caught— you don’t want perfect strangers to be caught either.  That’s the reason I used to flick my lights at people I didn’t know.  I was projecting my desire to not be reprimanded or punished by letting other people know how not to get caught.
