Drive Shell feature allows us edit the agents after making agent cache. Usually we use it to fix some agents translate or rotate, and hide some error agents.
Suppose we've already got the good simulation and made the agent cache especially we had did the dynamic simulation. But for some reasons we have to make a small fix on some very limited and specific agents. While we don't want to re-make the simulation cache again because it's time-consuming and may take some risk. At this time the Drive Shell feature can help.
