According to the (very limited) information available, all new cars are coming with 8 cameras. if you don't purchase EAP, the system only uses 1 of those cameras, if you do, it uses 4, and if you purchase the full self driving, it uses all 8. Now, this has been hashed back and forth a lot recently with people saying that they must be using all 8 for safety, or they are wrong to not use more for whatever... but I wish that Tesla had simply stuck to saying "there are 8 cameras", (in their marketing materials at least) and talking about the FEATURES you get in the base model, or EAP or FSDC. By mentioning them though, it means that if next year it comes out that they are using all 8 for the base safety features, there are going to be people who feel like they are being cheated by not getting all 8 used for EAP. or if it turns out that they really only need 3 cameras for EAP, we might get annoyed that we are not getting all 4 of them used. it also opens them up to people saying that "if they had only used 6 cameras instead of 4 for EAP, this accident (or whatever) would never have happened. To me, If I purchase EAP, and expect the car to automatically exit the highway, I expect it to do so in the safest manner it can with what it has, if they only need 1 camera to do that, fine, but if it needs 5 cameras, they should be using them. (and I HOPE they actually are). I don't get to see the feed of those cameras, so it really shouldn't matter to me if it uses 1 camera, 4 cameras, 5 cameras, or NO cameras... as long as it works reliably and achieves the stated goals. I know that there are physical things in the car that I ordered that will not be used because of the options packages I chose, from harnesses that are unconnected, to sensors, fuses, mounting plates, and even the extra 15KWH of the battery (I ordered a 60). This doesn't bother me at all, but those extra un-used cameras do kind of bother me, though I will admit they shouldn't, I think because they made a big thing about them. Note: It would be good to see this kind of thing covered in the manual so we knew that if camera X was broken, we would lose features Y and Z, but from a marketing POV, all this seems like it does is create confusion and potential future ill will.
