It's interesting for sure. I think alot of it comes down to the mindset many people have of, "it won't happen to me". At least when it comes to lightning, I don't think people truly respect how deadly it can be. Same goes with flooding, most people don't realize how powerful moving water is. It's hard to totally fault people this because the education on this is lacking but it's definitely become better over the years with the awareness provided by local TV mets, NWS, etc. But there needs to be another element to this. It's probably something that should be incorporated into sciences courses beginning at the middle school level - I'm sure it probably is in some districts but how in-depth, not sure.
At least for myself, I am extremely cautious when I am outside when there is an approaching storm. Even if the storm is a good 15-20 miles away. If I am outside with the camera I am right next to the car door with the door open or if I'm at home I'm very close to the door. I'm pretty mindful of the objects around me and what they are. But all of this of course comes with my knowledge of thunderstorms and lightning. So I am thinking of things that most people don't even realize.
