Ie there'll be a whole heap of faults and trouble awaiting the 3rd or 4th owner 10 or 20 years down the line and it'll probably be uneconomic to repair if too many modules fail. >This inforgraphic claims that the average car has 100 million lines of >code which blows my mind: > https://www.visualcapitalist.com/millions-lines-of-code/ Quite ridiculous really compared to some of the other systems especially given most of it is in the bloated ICE which many people don't use anyway because they just pair their phone and use that instead. Why do car companies design the interface of cars for teenagers these days when the people buying them new are are usually 20+ years older? One of lifes mysteries.
