I found the following anecdote on Quora
Many years ago, I worked for a gas & electric power company, and had been a member of a crew installing a road-side gas main. Despite the signs, flashing lights, and traffic cones we'd set up well in advance of the work zone, the overwhelming majority of people would speed past us--sometimes within an arm's length, seemingly having no regard for our safety. Our supervisor showed up to check on our progress, and, witnessing the danger, he walked to our truck, took out a yellow compressor hose, and rolled it out across the road. Immediately & without exception, from that point on, every single car slowed down before driving over the hose.
This is the worker's interpretation of the behavior:
In my youthful mind, I concluded that people were simply more concerned about damaging their cars than they were about damaging other people, but in my now middle-aged mind, I believe it's more complex than that. Maybe it's one of those countless subconscious, split-second decisions our minds have to make throughout each day, assessing probabilities & adjusting accordingly: 'I see the road crew, I've never struck a person with my car before, it's much more likely than not that I won't strike a person today, and those people are aware of my car & have the ability to avoid it, therefore, carry on.' [versus] 'I see an object on the road, I see that I can't avoid the object, I've experienced damage to my car before when driving over objects in the road, and that object isn't going to move, therefore, caution is merited.'
Is this interpretation correct?
