If you're like me you just want a car that get's you from point A to point B reliably and safely. You're probably thinking they will always be an option for a straightforward mechanical machine.
But that may not be the case. Regulators are increasing demands for more and more electronics and a lot of that is driven (I assume) by car industry lobby.
Essentially, the best thing a car industry can achieve is to turn your car into a computer or iphone. This way they can release new models every year and increase the the pressure to buy more.
Right now a 20yo car is still good to drive around and not that much has improved, but what are you going to do it the new software update is no longer compatible with your car? :)
And obviously, more higher complexity.higher failure means more profits on component sales.
