Is it even possible for the these behemoths to exist when the demand for cars is decreasing and alternatives are exploding with the advent of batteries and electric motors powering every mode of transportation from bicycle(I love my Ebike) to skateboards? And is it possible for the suppliers to survive when you have so many fever moving parts compared to ICE cars? For me the car feels like the horse a hundred years ago. Dirty smelly heavy noisy and soon obsolete.
