where does that article state aluminum is easier to recycle than anything (let alone steel)? It simply says aluminum recycle is good. Of course its good. So is all recycling rather than consuming additional natural resources. The point is, material of construction should not be dependent on any one issue. There is no "one size fits all", it depends on the application, the market, safety concerns, the cost of materials, etc. Any design that favors a single material of construction just for the sake of doing it isn't practical. Its a concept car. That's it.
