The Wife and I have hitchhiked a few times and when we got a car we decided we'd return the favour by taking hitchhikers whenever we have free seats. So far, we've taken only a few people for short distances (mostly students, and one very old lady), and only one person for more than 300km.
I've looked at Polish and European webpages for hitchhikers, for example
RoadSharing.com or
AutoStop.pl/.cz/.sk. Once your register, you can fill in when and where you're planning to go, what time, how many empty seats you'll have and if/how much you want for the fuel. Or you fill in where and when you want to go. Then the service tells you if there is a match. Other than one-time trips, there are also cyclic commutes. We haven't used these services yet (there are so many!), but from monitoring them I've noticed that there seems to be enough interest to keep it going.
The software in the vid is cool, but maybe you could start with a web service for your area? Post where and when you'll be driving, and get it advertised. You have to start from somewhere...
