I hate to mention this...but I wouldn't want to have you as my
mechanic.  :-)

The wheels of a car *do not* rotate one way on one side and the opposite
on the other.  You have simply changed your frame of reference.   Roll a
bicycle forward.  Standing on one side of the bike, the wheels are
rotating clockwise.  Stand on the other, they are rotating counterclockwise.

A car would work without a differential in much the same way a wagon or
cart would.  However, when cornering the tires would need to rotate at
different speeds.  This would tend to cause slipping on one side and
dragging on the other and lead to control problems as well as damage to
the tires.
