I've never understood why people let them run on, get in turn everything off, stick it in gear and lift of clutch and stall!
Or have I missed the concept all together?
I was thinking the same, but as mentioned, not sure how you'd do it if auto.
TBH its worrying in those video's how unaware of the dangers people are, I'd be running fast, not uncommon for conrods etc to be ejected through bulk heads and out of engine bays in those circumstances!
