This idea involves the pre placement of 4 jacks, one for each tire. When you have a flat tire, you would simply press a button in the car to engage the jack you need to lift that section of the car where the tire needs changing. This eliminates the need for onstar, or AAA service calls. This also eliminates the hassel of having to worry about finding your jack, placing it under the car and cranking it up while dodging traffic. This is a concept that could be used for any car, SUV, or truck. As far as i know, this idea does not exist yet. I do not have a patent and would be willing to give the idea to Ford free if they would use it on their cars etc. I beiieve that there are many people that can benefit greatly from this idea. I welcome your feedback. Thanks Ilar
