The US was ahead of the EU in requiring backup cameras on new vehicles.
The majority of pedestrian accidents aren't involved with backup cameras.
Are you just trying to turn this into a US vs EU argument?
Americans drive significantly more miles per year, and larger/more comfortable cars are in part needed because Americans spend far more time in their cars than Europeans.
Euro governments are also increasingly anti-car, which means citizens are loosing their freedom to travel as they wish and unreasonably taxed, policed, and treated like cash cows for the "privilege" of driving.
Most of my European friends brag about how they can get anywhere via train and how much more comfortable it is to travel that way. When I visit Europe I have to agree. Just haven't really seen this viewpoint, though I do think I would feel this way as an American if I moved to Europe to some extent (though I'd be extremely happy to have viable mass transit).
So pedestrian deaths would start rising again.
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 suspect older children are more likely to be able to be aware of their surroundings and have better gross motor skills to react.
