Well you compared a plane to a PS4, not me. Planes go through many years of safety testing before the public can go on them For example, the first time an Airbus A380 flew was in 2005, for 2 years it did all kinds of safety tests. The first time the public could go on a flight in the A380 was in 2007. The PS4 does not go through many months of testing to make sure they don't die. The hardware for the PS4 hasn't even been around all that long.
Medicine, like planes, need to go through a lot of safety tests before they can be given to the public. There are loads of cures for loads of different forms cancer right now, but they aren't available to the public because there is a high chance of them doing more harm than good. Those cures are going through loads of different safety tests and quite a few of them fail. The medicines go through many months and years of testing to make sure they don't kill people. There are some cases in the past where medicines weren't tested properly, given to the public and some people died because of them.
Part of train track maintenance involves stopping plants growing on the track. Train tracks usually go under maintenance after 1-2 weeks of them being built. High speed train tracks also have to go through years of testing before they can be built for the public to use to make sure they aren't going to fail under the weight and speed of a fully loaded high speed train.
The food example you originally said was pretty stupid, new foods aren't being tested all the time because there aren't any new foods. There are occasionally different combinations of that food that is being made, but since there are no new never before seen ingredients, they don't need to be tested. However pesticides (that are used to spray on crops for human consumption) do need to go under a lot of testing before they can be used by farmers to make sure the pesticide doesn't have a negative affect on humans. Those go through pretty similar tests as medicines.
If you want to make a proper comparison on failure rates of the PS4, do it with other electronics that have brand new never seen before hardware.
I've heard Sony didn't inspect and test PS4 consoles if there's something wrong before PS4 launch. I felt like Sony selling the Prototype PS4 consoles on launch and treating customers as the rat lab. Not fair!
No wonder Developers using developed PC instead.
