Cars engineered to be low maintenance. I think not. Car engineered to be assembled on a production line. Large components bing bam thank you next. That is till they require repair.
Like a switch in a mates European car. $154 for the switch. 4000$ to change it. Requires the whole dash and most of the engine to be dismantled to gain access to the dash bolts.
The philosophy of aircraft has not changed and never will. Something that not a large requirement in a motor car.
