The most famous car sharing site was bugride.com, but this seems to have closed down now. It is no longer as easy to find car sharing websites as it used to be, but with the price of gas so incredibly high and the threat of climate change on people's minds, there has never a more important time to carshare.
It is as easy to offer a ride as it is to look for one on these car sharing sites. So if you're planning on renting a car in Spain, why not advertise on one of these sites yourself?
Car sharing is an old practice. "When you drive alone, you drive with Hitler" was a car pool propaganda poster from World War II, which I have seen adapted for the present day (swapping "Hitler" for "Bin Laden"). I'm not sure car sharing is the most effective anti-terrorism move in the world, but it is certainly good for the environment.
Car Sharing Resources in Spain and the Rest of Europe
- Hitchhikers.org
Not about hitchhiking at all but the car sharing website with the most journeys on offer. Browse rides over the next few days or search for particular destinations. Hitchhikers.org has subsections for Europe, Asia, Africa Oceania and the Americas. - Compartir.org
Doesn't let you browse, which is annoying, but it does have lots of rides on offer in Spain (I found 48 from Barcelona to Madrid). - Drive2Day.com
Though the site is in English, the drop-down menus are in German, which can be a little irritating. Also doesn't allow browsing, only searching.
