If your goal is avoiding bad outcomes, you change the environment to avoid bad outcomes.
Even outside eliminating cars, things like sharp curbs and physically protected bike lanes save lives, especially children's lives. If the goal were saving the lives of children, you do that first. Instead, over my lifetime, I have seen these things disappearing. Literally becoming more dangerous.
I know you think you're arguing in good faith, but you are a puppet of some seriously malevolent mother fuckers who will endanger children for profit and an excuse to fuck my privacy. Yours too, if you care. Don't tolerate a hand up your ass without at least a little foreplay.
Edit: change the environment or train people
