Bench pressing and the chicken wing

I often see lifters doing the bench press with their elbows out, under the bar.  So there arms are parallel to the bar and at a 90 degree angle to  their body.  OK, is this how you would push your car when it is out of gas?  Or is this how a football player pushes another on the line.  No, your elbows are down, about 45 degrees to the body.   I know, I know, it makes the bench feel easier, but it is training the body to do things in an unnatural motion.  This works against your motor skills when strength is needed.
