So I like to go through the car tag, both the general car tag as well as specific makes, but I've noticed some inconsistencies in tagging, not just with tagging but with the tags themselves for the makes of cars.
Let's look at the tag categories using post #2590451 as an example. We can see that the Lamborghini Avendator, the Porsche 911, and the Chevrolet Corvette (which is the only 3 cars detailed enough to be identifiable) are all tagged with the makes and model tags. However, Lamborghini is the only one with the copyright tag, while Chevrolet and Porsche are General tags. I've seen previously that car makes used to all be Copyright tags, so I went to fix that, but I noticed that the Chevrolet tag has been category locked to be a general tag, while Lamborghini is still a copyright tag.
Also, if we look at post #2531690 this isn't even tagged outside of the generic tags for vehicle and van. Although there's a little confusion with that post, which I'll leave to the comments of that specific post.
I know the tagging of cars is something reserved for people who can identify specific makes and models, but perhaps we can reach an agreement on categorizing car makes. As I said before, all car makes used to be copyrights, but after Danbooru changed the way that tags were presented, I noticed that this is when it fell into disarray.
