Not sure if you are referring to the Civic or the Wira being a Milo tin?

Either way, ppl need to depart from that old mentality of seeing a smashed up car and assuming its a milo tin. That's the crumple zones and its specially designed to crumple and absorb the energy from the impact by controlled deformation. If this energy is not absorbed or dissipated, it will be directly transferred to the passenger cabin. This is basic Laws of Physics.

Newton’s first law states that an object in motion will stay in motion with the same speed and in the same direction unless acted upon by an unbalanced force. As a result, if a vehicle is travelling at 110kmph, the passenger bodies inside are as well, and if the vehicle hits a solid wall and comes to a stop immediately without any crumple zones, the bodies will continue going in the same direction at 110kmph.

Passengers will continue to move forward at the same speed until they come in contact with a part of the automobile or another human being, causing severe injury. Even after a human body comes to a stop in an accident, its internal organs continue to move, slamming against each other because of the impact, often causing serious internal injuries and bleeding.

That's why crumple zones are very important. But crumple zones need to be paired with a strong passenger compartment to prevent intrusion or structural collapse.

If you walk around the Civic and do the 'knocking assessment' you will find a lot of hollow sounds. Being hollow is ok because it means that there is internal space for the crumple zone to collapse and its energy absorbed. In most continental cars like BMW, Audi, Merc and VW, you will find less 'hollow knocking sounds'. This is because these manufacturers generally include a lot of energy absorbing materials within the crumple zones. Try closing the boot of the BMW 5 Series for example and ull understand what I mean. But if the Civic were to follow the same route and include all these energy absorbing materials within the crumple zones, im certain we will be paying about 100K more.

Most importantly, Honda has done a very good job with its chassis and strengthening the passenger compartment. That's why the Civic gets the highest crash rating of Top Safety Pick Plus by the Insurance Institute for Highway Safety America (IIHS).

It also obtained a 5 Star overall crash rating by the NHTSA with individual 5 star ratings for frontal crash, side crash and rollover. Just for info, the 2015 BMW 3 Series also obtained an overall 5 Star rating but only got a 4 star rating for frontal crash.
