You could envisage technical solutions for some classes of these errors, but they would usually require huge changes to infrastructure or only work for new cars. And full self-driving is still ways off.
I view the overwhelming majority of driver errors as faulty system design. Instead of red lights use turnabouts like in Europe.
I just came from a small town in France where they put these staggered obstacles on one side of the road which forced both directions of traffic to be merged into one lane. So they forced people to drive into incoming traffic thereby causing cars to drive slower. A really low cost solution to slowing car speeds in the busy pedestrian area and making the roads safer for pedestrians.
Most people think they are good drivers which makes them immune to actually getting better through training. As for process, good luck implementing it if you can’t train it.
