Touchdown! Greaser!
The never ending useful load discussions. I wonder what would happen if you just used your judgement to determine the maximum load an aircraft could take just like a pickup truck? Would more people crash, would pandemonium break out, I doubt it would skew any actuarial table. I've flown airplanes that were legal yet right on the edge of a serious problem. Others at max gross you'd think it was just you and a quarter tank of gas. Not to mention some very questionable pieces of paper (STC's) you can buy to make you feel good about the load you're carrying in certain models.
The real question should be, would you rather fly a 180 or 182 with 4 people?
I've spent plenty of time flying 182s with 5 people. They are most certainly the better airplane, IMO. But A cherokee 180 can meet many people's mission for less money.
