car rig

so, i got a small job in recreating a scenario invovling a lot of cars that has to be animated, how can i rig the wheels of the car so that they rotate when i move the car? so i dont have to animate it manually.

keep in mind, the car will rotate.

This seams to be the most reliable method:

I think a lot of the rig could be simplified, but the main goal of getting the wheels to rotate correctly over the course of an animation (and in any direction) should be easy to replicate.

Good luck!
