How much should a crash test dummy be paid?
Think slavery here – it is an asset that you paid for one time, and it does not even eat. It does require spare parts from time to time, and eventually needs replaced, so the depreciation plus maintenance is salary. A human’s spare parts would be much more expensive, they need to eat and make a buck, and they have by far a shorter career expectation to replacement (mean time between failures, too), so comparing the apparatus to a human is really a non starter. Unless you can sell the reality show like Jackass, regarding the situation as salaried compensation makes little sense. Moreover, you can put better quantitative sensors in the dummy than you can in the human, so you will get more reliable data.
