Physics: how to make the car run smoothly

I have tried to make this project as the example but why my car can not run smoothly.

Is there anyone can tell me what is wrong about my project?

I'd take a look, but do you have a Dropbox or Google Drive link instead?

OK, I see the problem - looks like the image points you're using as your joint locations don't actually line up with the centers of the wheels. Set the wheels' opacity to 50% so you can see the body of the car behind the wheels, and then line the centers of the wheels up carefully with the black dots on the body.

Oh, nice!

I think I didn't understood about physic revolute joint, so they must be justified on design time to make it run smoothly.

Thanks for your helped!

You're welcome. You could also set them at runtime with "set position to another object" actions on the start of the layout, if you want it to be more precise and automatic.

But now, I'm using physic torque instead, so I can make it more realistic as car wheel rotation
