Well the thing is still that the weighted necklace pulled by 1.5 to 3 tesla towards the machine will also put it the machine out if comission from several days to several months.

Also the down time of the machine depend from so many things like availbility of components, logistics and the actual damage happened, that even the most pragmatic operator could never calculate the price of the repair versus the value of the possibility of saving human life.

FFS the saved 30k only buys pretty decent slightly used car. Its sick to even start to weight that kind of money to human life.
