Now there's a point, because I accept the assertion that flying 10% overgross is safe, I must also be asserting that drunk driving is safe. By extension, you are asserting that I think 10% over any limit is OK. Hmmmmm.
I would suggest that your analogy is ill considered. There are any number of reasons why it does not pertain, not least because, as far as I know, there are no existing notification/application procedures for getting approval to drive drunk.
May I suggest that if you are going to analogise you try using one that is analogous.
I am not sure what the procedure would be to get approval for 10% overweight in a 737, but I'll bet it is not popping a notification in the post within 2 days of making the flight.
