Motion creates electricity, there is plenty of motion in a car (4 wheels constantly turning while driving)... so why haven't they used what's already there to create an electric car actually worth buying?

Already done!
When you step on the brakes, some of the energy from your car's forward momentum is pushed into the ground, while the rest is transformed into heat, slowing your car down.
In an electric car, stepping on the brakes uses the spin of the wheels to turn an on-board electric generator that puts alot of the energy that is normally lost in regular brakes, back into the battery. This is called "regenerative braking".
