You're completely retarded if you think that we can't find ways around that. There are water based lubricants. You can make fuel out of alcohol. Just because oil is in so many things NOW doesn't mean it always will be. We should start working on something more permanent, because furthermore, there won't always be oil. If we are entirely dependent on oil, and it eventually runs out, we'll be more fucked than ever. It would be better to start spending money on something practical rather than trying to control what little scraps of a dieing system.
