I personally choose to bike, but if I started making charts about the relative energy consumption of the two, I'd reach a similarly obvious conclusion. If I used those charts to convince people to start biking, I doubt I'd be very successful, since people usually have strong preferences to one over the other.
One difference in this analogy is that cars pollute, whereas I couldn't care less how much memory your computer is using because it has practically zero impact on the environment or anyone other than yourself.
