I'm interested to see how the driver story is going to be implemented. It seems like it's going to be AA drivers which makes sense, if something was to happen to the driver, the vehicles are tall enough for the AA to drop out of view from the guests. After all, we're only going to be viewing through a small partition anyway which I imagine will be frosted or something when we get into the vehicle and then will become see through or whatever when the ride starts.
For a lot of the guests, whatever happens up front won't really matter visually because they'll be that far back. Looking at the sketches, it looks like there will be 12 rows of 6 for a total of 72. For somebody at the back, looking through a small window from 30feet away in between 11 rows of heads, I don't think they'll see much.
they may pull an alien encounter with effects to make it feel you get hit with blood...lets not forget that's what Disney did.
If they use those see through screens, you could have blood sprayed on the window.
