I would argue we need a room like system,where a number of cars enter each room and you can set a path with car rotation and angles for the individual cars trough the room, also a station room,where you can set a individual station for each car and maybe an unloading station room. Obviously let us scale the size of the rooms. The current system of creating track for 2 or 3 rides and synchronising them is just way to hard for a ride system that has so many great possibilities in terms of darkrides. Since the 5 year roadmap leaks from when ghostbusters dlc came out (which have turned out mostly true) suggest they are working closely with disney on planco 2 however I'm pretty sure they'll improve darkrides and inside decoration a lot,since it's still been one of the strenghts of the first title and something people have done a lot.
