I bought a new energy vehicle, and the salesperson said the range was 500 kilometers.

In winter, when using the air conditioning, it actually ran out of power after 200 kilometers.
I asked the salesperson, and he said, "The 500 kilometers is under ideal conditions; a 40% reduction in winter is normal."
I asked, "What about in summer?" He said, "An 80% of that."
I asked, "What about in spring and autumn?" He said, "No discount in spring and autumn, but there are only a few days like that."
I said, "Then why didn't you make that clear at the time?"
