Worst Case Scenario

I've watched this sorta new show on Astro called Worst-case Scenario. Its a very educational show and yes its applicable to our everyday lives. Why do we have to be pro-active when it comes to our own safety? Can't we always think of a contingency plan in case something happens.

Recent examples like the fallen road due to human error. I'm sure that before this incident has happen, nobody cared about the hanging roads supported by a thick beam above busy roads. Now? I think everyone would think twice about stopping directly beneath these pillar for fear of another Human Error...
