generative car music

Imagine driving a car on the highway and have music that is "generative" meaning an onboard computer is composing and creating the music on the fly. For instance as you speed up or slow down on the highway,the music raises and lowers in beatrate, or as you change lanes, the violins play some sub-melody.

Every time you drive your car, it'd be a different experience. Many things would influence the music.. you choose a genre, like techno or classical. and the onboard computer takes into account your car's speed, the outside temperature, the direction you are going, even things like the amount of gas you have or how well your brakes are doing..

After a while you would develop an intuitive "feel" for your car so that while you are listening to the music, you would "know" that you were running low on gas, or that your transmission was off somehow... the harmonics would feel "wrong" to you... This would almost be like another "gauge" - only it uses your asthetic sense of music, tone, rhythm, etc. to help you know what's going on around you.

Other things might be the music adapts to the presence of other cars around you, so you might begin to learn how to "sense" the cars around you through the music..

This is all assuming that the music responds to the same stimulus in the same consistent way...
