The question is here: Did the US ban the Volkswagen XL1 for being too fuel efficient?
More than one person has commented on it saying that asking about motivation is off topic. That's fine, my actual question isn't asking someone to read minds. If the car is indeed banned for sale in the USA, there should be a reason why listed somewhere in public record, which is what I would like to know.
I'm new to Skeptics, but not to Stack Exchange as a whole (75k on SF). Can someone tell me what faux paus I've apparently committed so that I can avoid it in the future and have comments be more focused on the question rather than how I asked it?
