No, it really does. I've tried without dot and all it does is a little amount of smoke. Dark dot makes rubber absorb more energy - it gets more hot and pops. More powerful lasers don't need the dot and more weak won't pop the balloon even with the dot.
In my country it doesn't. It could turn off street light if it had photo sensor that tells it that it is so bright outside and automatically shut down the light. We have centralized street light control which don't have such sensors.
