This has got to be the funniest on-board video from a rally event we ever had the pleasure of watching.
The footage was recorded during the 2013 Rally of Coimbatore which is part of the Indian National Rally Championship. Driving the Mitsubishi Lancer Evolution 10 is Samir Thapar with assistance from co-pilot Vivek Ponnusamy.
As you can see from this video, the co-pilot is terrorized by Samir's lack of driving skills and/or his poor abilities of listening to the indications. At the 1:09 point you can hear the co-pilot screaming "medium left" for a couple of times but this doesn't stop Samir from going off-road and almost hitting one of the bystanders.
While the co-pilot is nearly having a heart attack, Samir Thapar appears to be very calm judging by his voice. One of the funniest moments is at the 3:47 mark when Samir says "shut up, don't tell me how to drive."
