I must say this the first time I am learning about the term 'crumple zone'. Thought seat belt was the all in all during car crash.

You are so right with the condition of the road over here. Most times traveling is like hell. It is now a routine thing for me after travelling for a long distance through land, I must take pain killer to suppress the headache and pain accompanying it.

Most drivers run as if the vehicle is on air, especially the inexperienced ones.
Though most transport companies now install speed limit devices so as to keep their drivers in Check, peace mass transit, GUO are few of the ones that maintain this standard.

Traveling by land though has it own advantage in terms of survival during accidents, but in the case of travelling by air, you hardly hear of any survival.
