The Yugo had problems, but it also had the right idea: a cheap, fuel-efficient, sensibly sized car where the only point is transportation from one place to another. Cars as conspicuous consumption has been a disaster for the planet and for society at large. The end goal is to move away from car dependency and toward actually sustainable transportation — but as long as we have cars, small and fuel-efficient is the standard by which we should build them.
The Yugo as a foot soldier in the war against cars? Checks out.
