A Puffer is a car running unattended during cold weather. The exhaust is visible and a car thief grabs the car. I plan to use an older car so that I am not upset=20 if the thief bangs on the car. I plan to use long=20 distance video recording or local, remote control video to capture the action. What is the best/easiest way to disable a running=20 car ? The key will be in the ignition as I know of no easy way to leave a car running without the key. Maybe there is a way to make it look like exhaust is exiting the tailpipe. Then the car will not be running and will have =93fake=94 key in the ignition. I look forward to creative suggestions.
