Proactivity v muddling-through

In a post from in October last year (2017) I praised Paris city government’s plans to ban diesel-engine cars from entering the Paris capital. But in a blog post yesterday, 6 months later, in Feb 2018, I argue that imposing diesel bans to combat polluted air in German cities is neither a novel idea nor an effective one.

Why do I appreciate an identical measure in one context (Paris) while I seemingly over critical in another (Munich, Cologne, and Stuttgart)?

Paris city government acted proactively. It tried to find an acceptable solution to a severe ecological and public health issue.

Germany’s federal government simply ignored the same problem for years. Despite EU regulations it took judges to induce any policy actions.

So the difference is between Proactivity and muddling through. I appreciate the former behavior why I disguise the latter one.
