Sadly personal use cars are a luxury for the majority not a necessity, as much as they'd like them to be thought of that way. The problem is people want the convenience but don't want to give it up if they can't afford it anymore, we live in a society now where want/need are so easily confused. People who have great PT links don't/won't use them, and those that need them and don't have them end up in a difficult position. I'm happy walking, cycling, using the bus/tram or train for nearly every journey I do, and could easily get rid of a car if I had to, the money saved would easily pay for a rental/taxi etc. on the few occasions I needed one, not everyone is as flexible or can frankly be bothered.
