I can't get my car to work

I’m using this tutorial Vehicle User Guide | Unreal Engine Documentation
and I can’t find what I doing wrong. I’m using my own simple car but I did the bones correctly. I’ve gotten it to move by making it teleport forwards every game tick while I hold down a button but this is not ideal. I’ve followed the tutorial exactly and I’m not sure what’s going wrong or how I can fix it.
