We'll have to agree to disagree then.
You see the problem I have is that based on the rides design I have a mental image in my head of what the carts need to look like in order for them to be able to function. Things like the rough width between each cart, its shape and proportions ect... remember I studied Engineering, I kind of have a feel for these things
Anyway the point I’m making is that most of the marketing does not match up with this. To me everything about it looks wrong... except for two pictures, the one in Mutiny Bay (see below) and the one from The Sun. Both of these two images have proper engineering proportions but more importantly are unique and not a re-coloured version of some other rides trains. Therefore I am in no doubt that these are what the trains will look like.
As it turns out both of these images show a design that appears to have lap bars, therefore I must conclude that this is what the trains will have. Simple logic.
This design is just too accurate to have been made just for marketing purposes:
