There are other places I. The world where this is not true. For example, more than 50% of all households within this S-Bahn ring in Berlin (let’s call that the extended center) do not own a car. The bike may also replace a second or third car. Not counting the cost of manufacture is just sloppy.

They also picked a car that is twice as efficient as the average car for comparison and the most meat-heavy fiery possible (essentially meat only). That’s interesting as a though experiment, but not as a basis for policy- which is exactly what they state in their preface.

Yeah, it's not for policy, otherwise it'd have to target a particular jurisdiction too. It's for individual interpretation. If you eat a lot of meat and own a car and a bike already, maybe think about biking more as a healthy exercise than a way to help the environment, or think of meat as a bigger problem for it.
