Ok here's the idea. Its simple really. You build a co2 laser, a big one, a really big one, and rig it to run off of the twelve volts that come from your alternator. if you need more power, install a second alternator. Then place the head of the laser in such a way that it points into a mirror under your car so that it can be focused on any point in front of your car.

Now the infrared heat a co2 laser emmits isn't particularly usefull with metal, or glass even. But it does a great job at punching holes through wood , plastic and rubber. (think rubber tires, getting the idea yet?)

Then place one of those cheap minature black and white video cameras on your front bumper and hook it up to your computer. Those cameras can see infrared light. Have a regular $8 laser pointer hooked up in tandem with your big co2 laser so you can aim. Hook the video camera up to a computer. Have software taht recognizes the heat trail left by the tire of a a car (wouldn't be hard to write at all). Then have the software driev the stepper motors hooked up to the aming mirror. Have the software recognize the little red pointer laser so it knows when its focused on teh middle of teh tire (the weakest point because it will be under the most pressure, and its tempreature will be higher). Once the software has 'locked' onto the tire of the car infront of you , you can push a button, that should have your co2 laser pulse ever 1/4 second or so... (pulsing a laser incresses its power output). And BANG, they have a blow out.
