I don’t really know how to understand the site in this context, since it says bicycles produce zero carbon emissions, so it can’t be taking vehicle production into account, and the topic at hand is resources required in production. And battery constituents at that, not carbon emissions.

Also: buses are empty when the service is shitty. It’s being proven every day that people choose the method of transport where the offer is good, be that car centric infrastructure, bike paths, or convenient public transport.
