Some tracked vehicles could only stop one while driving another, this don't allow turn in their own center (mainly because they don't have a mechanical reverse for one of the tracks), others can reduce a little the speed of one, so it can still drive at some speed and make little curves. The only exception is the castor wheel that is not part of the system, just an example for balancing.
