NZ OP here. Few weeks ago there was a morning checkpoint to inspect everyone's child car seat installation.

Few years back got chased by a cop and ticketed (and scolded) for not restraining kiddo (small town and my clever 2yo somehow learned how to unbuckle themselves (even that houdini clip didn't help)). Warned I could get prosecuted for child neglect if I continue. I suspect the daycare has tipped him off.
