Same in France, there's a very popular site with several millions of members: http://www.covoiturage.fr http://www.covoiturage.fr I used the service myself and they have plenty of good ideas, feedback, voting, preferences, good ride search etc. I myself wanted to start a ridesharing site some time ago but it seems like a tough proposition as it's very much a chicken/egg problem. Good luck with this new site though, we need more people ridesharing in the world :-)
