By the way, this is the first time I've participated in a multi-car puzzle and I'm not familiar with the generally accepted practices. There is a general AP rule against simultaneously asking more than one question about the subject car in an individual-car puzzle (which makes very good sense to me). However, whenever someone has created multiple individual-car puzzles, it has always been acceptable to simultaneously ask questions about each of the different cars in their respective threads (which makes just as much sense to me). In the present scenario, with multiple cars in one thread, is it acceptable to simultaneously ask questions about the different cars? In other words, is it 'one question at a time per thread' or 'one question at a time per car'? Thanks!
