- Car. In parking lot. Sounds pretty mundane so far. Pretty much they're parked or on the road most of the time.
- Unattended. This is what you do after parking your car. You leave the car unattended.
- Gasoline smell. Near gas powered car in parking lot which may contain other gas powered cars. Occam's razor.
Pressure cooker inside. Are we that far gone we need to fear kitchen cookware? What about a cast iron skillet? Knife set? If your "further action" involves anything more than cooking tips (a pressure cooker is a great cooking tool) then you're jumping at shadows.
