It would be excellent to see information such as this put in front of people more. Most people don't have a clue how much it costs them to own cars, and most people think the thing they spend the most on is gas. Certainly they have hernias every time gas goes up a few cents. But they don't blink when they choose to buy a fancy car to impress their peers.
People don't factor in the cost of car commuting when choosing to buy a plastic palace on a big lot in the 'burbs or countryside as opposed to a smaller place that's more urban or next to transit.
Which brings up another matter. Transit systems are always stressed for money. They have to choose between trains and buses. Service levels vs expansion etc. The public observes this and has opinions about service levels, fare costs and subsidies.
A useful perspective is that the average person spends something on the order of $350 per year on transit fares and subsidies. While they're spending $10,000 per year per car. Well, what sort of useless transit system do people think they're going to get when they spend such a pittance on it?
Wait, there's more... The AAA graph is blatantly deceptive because it doesn't include the thousands of dollars per car spent on obvious subsidies per car, such as roads and traffic policing. Sooner or later this money comes out of the pockets of everyone including car owners. And even that does not include costs that are externalized, such as gobbling up valuable land, all sorts of pollution, accidents and driving up the price of fuel.
Societies can't make rational decisions when people have such a distorted or limited grasp of issues.
