In order to use fast travel, a player character has to register his DNA with the receiving lifenet station first. This is done by leaving a sample at that locations computer. Fast Travel then is initiated by killing the clone in one station and by reviving him at the receiving station. This process does not include mounts and vehicles. Check with your local garage or stable manager to have your ride towed. As usual, towing is much cheaper if mounts and vehicles are parked, prior.
