Although improving your actual riding skills will no doubt help, road craft will also give you better techniques to increase you observational speed, many riders are able to go fast, but a fair few exceed their own observational speed to do this, with the inherent risks involved.
whilst some don't have a health degree of concern over the hazards out there, it's generally because they don't see them, this may mean to start with improving this skill could even slow you down as you'll spot more potential hazards than before, however you will have increased your safety margins a fair bit, so will have tomorrow to keep practicing
