Alternative to pushing car as way of generating compression.
Novel idea.
Yeah - nice bit of lateral thinking - I’d of thought getting the wheel turning on a car in gear in that manner that would be quite difficult - but he starts it just like a chainsaw! :w00t:
That method has been used in Karting for years. 
Clever
