Working around the limitations of polytoria, here is a physicfree car.

Yup, it might appear laggy. Yup, it just hovers over the map edges. Yup, no collision - Its fully without any physics since Polytoria doesnt support them properly... you cant even clue stuff together :(

It will sometimes glitch a bit due to network desync tho this shouldnt be that big of a problem, at least it wasnt in my testing.
