There’s the safety aspect of allowing room for the vehicles to overrun their preprogrammed course. It also allows futzing with the ride path. It also lets people see that there is no track.
You don't need a warehouse or a lot of room from a technical point of view, but if you want multiple vehicles in the same space you need space.
You require 19.7" minimum for egress with automated vehicles that interact with people (meaning people walking around them) plus whatever extra Disney puts on there for safety.
What really exceeds it is basically the safety bubble is humans reaching out or swinging something from the vehicle so that doesn't hit anything.
It wouldn't be for overrunning their course. Any vehicle that could over run it course or be inaccurate in its positioning by more than 5" wouldn't have been use din their design. Next time your in one of those attractions, look at the tire marks on the floor. They almost overlap perfectly within some margin.
