Funny (sad?) thing is, none of these you listed are hard to predict. The details of some issues are more complex (like global warming) but overall problem in a nutshell is not hard to understand at all. It is just common sense that a bigger/taller truck makes it hard to see pedestrians. People still do not care, some even pretend to not understand.

Most people will not care about something until it affects them directly and immediately. We can debate the reasons for this, but that time might be better spent in working around humanity's apathy. Maybe make renewable energy super cheap and easy, better tech to track pedestrians so as to not hit them etc
