What was the double negative? You haven't included one in your telling of the question ("Which of these is not an illegal place to park:" with the correct answer being "in a bike lane." - that's just a single negative...)
Ah, I hadn't thought of illegal as counting for a double negative - it's not one for how I think, but I totally see both why you said it and why it would be a double negative for some people! Thanks for explaining
