I don’t think it can be either, at least not efficiently. I took a look through the movement component and the NetworkInterface and there definitely is some move saving and smoothing that happens. The problem is that it is pretty daunting. Unfortunately even the wheeled vehicles use server side control so the only example is the ACharacter class. I wish Epic would have implemented it for all controllable classes. Or at least the initial framework. Probably asking for too much though.
