Having said all that, I'll get off the soapbox and describe some of the actual physical phenomena that are being loosely described in this thread.
Robot Myth Busters - Robot Turning:
Myth: Tank Tread Drives can't turn.
Math:
Read this whitepaper:

It is possible to design a tank-tread robotto spin on a dime. It is all based on the turning scrub of the drivetrain-wheelbase configuration, and the robot gearing.
Reality:
Using a reduced length-wheel base, (wide-body, or dropped-middle system) it is possible to create a spinning tank-tread bot. However, this may result in other negative factors such as the robot rocking back and forth between front and rear.
Overall:
Tank-treaded robots can be made to turn; however the nature of their design results in significant scrub, which must be overcome in some way.
