Billboard ads are banned in cities in New Zealand. Have been for a long time

It'd be great if all public ads were banned and digital ads were the only form. That way those who are savvy enough can also block the digital ones and live a completely ad-free life.

My annoyance is that regardless of how I lock ads out of my own home and devices, I will still always see ads for McSlop and Coca Cola everywhere I walk in my city.
