The spirit of the law is good, but who's going to enforce it?  HPD rarely enforces cellphone/texting while driving.  Yes I am aware they issued a couple of thousand tickets last year, but that's primarily in downtown Honolulu.  But outside of the city, they rarely enforce cars with extremely dark tinted windows where you can't see anything or anyone inside.  HPD does not enforce cars with stickers on rear windows.  I saw a car recently with full advertising across the entire rear window.  And this car had a valid safety sticker.  But I suppose HPD will camp near elementary schools to catch violators.  What does HPD do when they come upon a driver smoking with a child on-board in a vehicle with stickers across the rear window and illegally tinted windows?  50/50 he/she keeps on driving because that's his/her uncle/auntie/(other).
