That's rather interesting. Perhaps an intentional design flaw to sell high profit A/C compressors. Customer on the expressway looses coolant pressure on a nice day and does not notice and destroys the compressor and can't drive their car without replacing it even if they live in a climate that does not really require A/C.
I wonder what will happen when that car gets 10 years old or so. Many "basic transportation" 10 year old cars don't have working A/C.
