It depends on what you mean by 'extreme test'.
While it may be fun to find out if a phone survives running over with a car it doesn't provide any useful information for the general consumer who realise that such is not what you are supposed to do with phones. The example provided hints that you mean trying absurd uses of products that they were never designed for. My 13 YO self would like that, similar to that TV series that crashes, burns and explodes stuff in the name of investigation. My adult self not so much.
If you mean testing at the extreme end of proper use that a product might experience to see where the failure point is it would be more value.
So you do want to provide useful information or entertainment?
