I don't really see how car can be seen as exemplary labor saving invention. Steam engine, electric engine, radio communication, computer, internet sure, but car?

It's just a technology that allows you to build artificial horse that drinks stuff you can mine from underground and shits in the air you breathe instead of on the street you walk on. It surely saves some labor, but it turns so much on its head by increasing mobility and allowing for actions that were previously impossible that this labor saving part is pretty minor and is easily offset by paradigm change that car brought by.
