Toyota has already unveiled a prototype of its Pod concept car, which has headlights that fade from bright to dull and change color to indicate happy, sad or angry moods, depending on how driver inside is feeling. In a joint effort with Stanford University in U.S and an Edinburgh based company Affective Media, carmaker giant Toyota has made another leap into making a car that can read one's feelings.

Research showed that a driver's emotional state affected how well they drove: If they were happy, they drove well and if they were sad, they tended to drive worse. "This is next generation of car, which can detect what mood you are in," said Affective Media CEO, Christian Jones. Identifying what mood driver was in by detecting emotion in their voice was taking things a step further, Jones said. "It's not as sci-fi as it sounds. We already use our voices for different functions inside car. It's about giving appropriate information at right time." The in-car voice would talk to you in an attempt to improve state of your mood. The technology would not act as a counselor to solve complex issues, but it would be more like a "best friend" who could cheer you up at end of a long day," added Jones.

Why do we spend so much time and money keeping up finish of our cars? Again, it's an artistic matter, perhaps a combination of pride of ownership with knowledge that people somehow identify us with what we drive around in.

Car art isn't limited to just cars themselves. There are many forms of art that use cars. Whether or not you consider advertising an art form or a nuisance, many ads for cars -- or for other things but using cars in them -- are a significant part of history of car art.
