But then when yet another person comes up to you asking "what is that", "that is so cool" and wants to ask all sorts of questions, it all gets forgotten.Setting aside the "if it saves one life then it's worth it" argument. The lights, bongs and constant interruptions/distractions are more dangerous that what they are trying to inform the driver of.

The underlying issue is that goverments want to think for us and save us from ourselves. This creates dependent weak people and that is bad for mankind. We are going to end up like a bunch of French Bulldogs who can only survive if someone else takes care of them.
