Earlier quoted context omitted.
I agree with better news coverage (I'd argue it's more news coverage, in which social media plays a huge role), but I'm not sure I understand your point about more cars?

I think I would agree with that. I don't have kids, but I have a lot of nieces and nephews, and my biggest fear for them playing alone outside would be getting hit by a driver who isn't paying attention.
