yeah well when russians going offroad they mean it, because sometimes they can be stock in a midle of nowhere and go sleep and early morning keep going. Thats what happend with those guys they stock in water and it was dark outside so sleepy time and noone knew that running engine and exhaust undr the water can cause serious danger like that so they test out most popular cars people going offroad to warning people. I personaly wouldnt leave my engine running and sleep in a car with my windows close, you never know what can happend. I post all that on here you warning you guys if someone ever go offroad and stock in water do not run your engine and sleep.
