You can use Matchride as a "rider" to catch a ride with someone in your extended network and/or as "driver" to offer a ride to someone in your extended network. Maybe an old co-worker, a friend-of-a-friend, someone with the same hobby etc is going the same way without you knowing. With empty seats driving around for billions of kilometers, chances are pretty big that they are.

Depending on what days you have access to a car, where you are going, your mood etc, some trips may be more suitable to ride-sharing than others. You can plan your week up front from your calendar or catch/offer rides directly from your cell phone or car navigation system. Since Matchride can get most information directly from your phone, navigation system and/or calendar, there's only a minimum of work you need to do to request, offer, track, change, pay and rate a ride.

In fact, the entire point with Matchride is to make it easy and rewarding to share rides dynamically and "on-the-fly" instead of as a static/permanent agreement between one rider and one driver. Therefore you will not only save lots of money and tons of CO2 - you get to keep your freedom and flexibility.
