Car Maintenance

I am very slack about car maintenance, which is why I took care to buy the extended warranty when I got my car and why I am very worried about sudden failures of my car's machinery. I constantly fret about the oil level, the transmission fluid, and tire pressure.
Naturally, my mind is next occupied with solutions for my problem and the one that keeps returning to my mind is pain. Not personal pain, although if someone where to flog me each time my car needed maintenance, my car would stay in tip-top shape all the time; but what if the car "felt" pain. People naturally respond to and understand pain in animals and other people. If a car was apparently self-aware and could express sensations of pain to its operator cars would likely suffer from fewer maintenance related problems. Apparent self-awareness isn't as difficult as it seems. (although it probably isn't as easy as I am about to make it seem) The car would only need to monitor a few critical systems to keep the operator abreast of its current maintenance needs. With the advent of low cost wireless communication, engineers could disperse sensors underneath the surface of a car's skin and in the event of an accident the car could pinpoint the damaged area of the body. Better yet, the sensors could be equipped with short-range sonar systems so that the car could "feel" how close it was to obstacles in it's path. Imagine a car that could tell you how far to back up when parallel parking! What's more interesting is that nothing I have proposed requires new technology. I don't know about the price or practicality but I bet the majority of what I have proposed could be built with off the shelf parts. Why not? I wouldn't be surprised if someone is already working on it.
