Watching a second video in a few years of a well-trained and well-meaning adult demonstrate how hot a car gets in a short amount of time, with friends nearby but with doors locked.
I took exception to the demonstration for the following reasons. Ideally, the temperature rising could have been shown simply by videoing that from outside the car (even opening the door if need be and taking the temperature at intervals...the overall point would be clear still, that even a few minutes in a heated car can be dangerous.
