> How did we get to the point where reflexive empathy for drivers over everyone else has completely trumped basic understanding of both the law and human decency?

This! I sometimes watch some of these dashcam accidents, and I can say most of them can be avoided if everyone had some basic human decency, but it always go “I have the right of way I don’t care” attitude, yes you have a green light but obviously you are seeing other car is crossing the road, try to stop/avoid it instead it of ramming it, especially you are still accelerating not already at full speed..
