General awareness is a good thing and we can all work toward "better" awareness but situational awareness is not often something achieved by the lone person. Your "situation" as a commonly accepted term is much more encompassing that what most people give it credit of being. That said, we can improve our awareness by getting our heads out of tech (gadgets) and pay attention to what is developing around us. Of course, what we see does very little if we do not have the experience or knowledge to realize how those things effect or potentially effect our personal safety. I agree that many things regarding the avoidance of danger is rather innate but to truly be proficient in life-safety type observation, you need training. So, in short.. if you want to improve your general awareness routine, get some training. Until then, get your head out of your phone...turn off the buds in your ears, be present in the moment and give yourself the occasion to actually notice meaningful elements within your surroundings.
