This design could help people in an unknow emergency situation, for example, the driver pass out when the traffic accident happen, and this design can help people to save life. However, I think this concept design might be cost a lot if it is applied into real life, because it means there are lots of guardrail need to install this system, and the government also need to prepare another extra fee for repair the guardrail after every accident. 

This design is good for helping people when natural disaster happen. It is a housing  can offer 4 people and relief goods are very important for people after natural disaster. The pacaking is also not large and could be easier for transport. It is a good product for emergency and solve problems. 

Since the design used the aluminum alloy and steel as the main materials, the product cost should not be unaffordable for emergency uses. For the design, it is definitely attainable for the imagined user in a disaster situation.
