Perpetual motion machine

Now imagine, you’re in ‘space’ (no such thing) you fall off you space car in a spin outward to no where (energy used). Will you ever stop spinning? No air no friction never hitting anything, you will spin forever. Only on planet earth will Perpetual motion never work.

That's conservation of momentum. There's no change in energy happening, so the state remains constant - in the real world though there is no such thing as zero interaction, even in space. Eventually it all goes back to zero.
