The image is just an example to give you an idea. I kill myself with CO, but I burn coal outside until it stops and turns white, then I put it inside the trunk, locking everything. Approximately, I'll wait outside the car before getting in. How long does it take for enough CO to accumulate to kill me? I thought about placing a CO detector inside near the back window to see if it was measuring CO from the outside, but in Italy there isn't one that reaches 10,000 ppm and it's too expensive.
