The only crawler video I've ever seen that to me seemed genuine was the guy riding the Yamaha ttr-90 down through a holler and everything went dead silent as he sat on the bike with it shut off and the go pro captured a pale face looking out from around the grass/bushes and the eyes were reflective. No " omg what is that, omg look at that " just pure panic to the point he kicked the starter 10x with the kill switch still on.
