The US averages 23 pedestrian deaths per million people per year. The EU averages 8. The US fatalities have increased by 50% since 2013, while in the EU have decreased by 25% in the same time frame.

Collision detection sensors do the job just fine without a screen though.

I have a 2016 vehicle with no console screen and they have saved me from hitting all sorts on things, and are sensitive enough to detect minor obstacles like long grass.

I think the difference is that a 3 year old barely-walking child tends to wander behind moving cars far less often than an 8 year old playing football.
