Inside and Outside Car Smell Comparator

Is that burning smell coming from my car?

Have you ever been driving in your car and smelled burning rubber, oil or insulation? Have you tried to figure out if the odor coming from your car or the world outside? Did you have to decide whether to get off the road and find your fire extinguisher, or roll your windows up and drive faster?

Well, it happened to me just now, and I think the smell was coming from outside the car. I rolled the windows down and things smelled worse, then better as I kept going, and I got home without smelling anything else. But before I got here, I imagined an Inside and Outside Car Smell Comparator.

The comparator will have an air intake on top of the hood ornament or the roof, and another inside the passenger compartment. The two air ducts will lead to a battery of smoke and chemical detectors, and a gas chromatograph in the deluxe model. The two air samples will be compared, the data processed, and the results fed to a display.

If the detectors are numerous, and the microprocessor powerful, the display could be a screen that shows a variety of informative icons. A smoking factory, a garbage can or a clunker belching smoke would indicate that the smell came from outside your car, while trouble inside your car could be shown by pictures of a shaking engine, a fire extinguisher, or your Uncle Fred eating a burrito.

       ...but smells from outside the car could stil be coming from your car - e.g. if the car was leaking fuel or if the roof was on fire then the smell would be much worse outside the car.

       Hook it into a set of lights in the cars roof lining to illuminate over who in the car just cut the cheese. Make a model for an elevator!

       Quite true. I was going to write that it only differentiates if the car is moving above 45 miles per hour, then got distracted by making a smell analyzer out of it. My compliments on a proper use of "e.g.".
