An easily stolen car on a cold day. The engine has been left running while the owner goes back inside to let it warm up. The visible exhaust 'puffing' from an unlocked, keys-in-the-ignition ride tips a thief off to the easy grab.
Car warming up in driveway or left running in convenience store on cold day has tell-tale 'puffing' from exhaust pipe.
