Blame the EPA, California for more aggressive pollution and economy standards. You could still build a 1970s car today without chips, you just couldn’t sell it.
What do you mean blame? You dont want clean air? You want rolling coal diesels? and 7 liter 25l/100km family wagons?
Blame doesn’t always have a negative connotation. Obviously, the chips have worked well for us.
Highly inefficient death traps with no active safety feature and no ability to play music or tell you where on the map you are. Great solution there buddy.
