Like the drunken Russian soldiers we get to see dieing? In other words: I doubt it. Is there actual proof for this happening? If so, how would the effect of alcohol be countered?
I'm sure it worked the first few times. In a situation like that you'll be under constant stress, that's not at all comparable with suddenly finding yourself in an emergency.
I don't disagree with the first sentence but do disagree with the comparison. A driver is in constant control of the vehicle and has to make decisions on a second by second basis that could result in death. By comparison, the chance of anyone in an exit row even being in a plane accident is vanishingly small. Even smaller still the liklihood that they'll have to do anything (and be alive to do it)
Point being the event where you need to "drive" in the exit row (however rare) is a societal obligation, and should be taken remotely seriously (again acknowledging the changes are microscopic).
If you want to zonk out, at least do it in some other window seat so you don't impede an evacuation, however rare.
I wouldn't park by bike in front of a fire escape, as another example
