Thought about comparing different modes of transport, but realized it would be way too subjective. For example, if 5 km are in biking range is dependent on biking infrastructure, available public transport, how in shape you are...
But then I realized I can just simplify all these things away to get the optimal transportation flowchart. Simple is always better, right?
I'm too terrified of dying to an irresponsible driver, so as much as I would like to bike everywhere, I'll keep taking the metro for now. They're adding more and more actually decent bike lanes so hopefully one day...
