Let me throw out a “what if” scenario.
Let’s assume some guy was dating some girl. Let’s assume that they were walking down a busy street on a sidewalk. Let’s assume that the guy was walking on the street side while the girl was walking on the side further away from the street. Let’s assume a car came out of nowhere and smashed into both of them, killing them instantly. The fact that the guy was walking on the street side would have added no additional protection in the least.
Yet strangely, there’s a group of people out there who will always insist that it is necessary (if you care about them) to walk on the street side of the sidewalk in an attempt to keep them safe from the ambiguous dangers of the ‘crete. (Concrete, that is.)
