The thing is intent really doesn't even matter, it either makes you think of the 66 batmobile or it doesn't. For what we've been discussing, it doesn't really matter if it was intended or not.
It doesn't matter if you just say "It reminds me of the '66 Batmobie." It absolutely does matter if you say "They must have been copying the '66 Batmobile," because then you're not just talking about your own reactions, you're making an assumption about other people's motivations and choices.
