The reason CV's must be used in front wheel drive is because of the wheels being used for turning. If it was a drive shaft to the wheels, they would not be able to move.
Positive numbers were originally invented so that we could tell how much we have of something. For example, how many arrow shafts do we have, and how many stone arrowheads do we have to put on our arrow shafts?

It is used on extremely heavy vehicles such as dump trucks in a mine or locomotive. The design is: a diesel engine drives a electric generator. Then the electricity is distributed to electric motors that drive the road wheels. This design eliminates clutches, gearboxes and drive shafts. Today, some ships have similar design. The difference is the electric motors drive propellers instead of road wheels.
