Wheels teleporting and bouncing

Ok cool, I figured it had something to do with mass @AndrewGarrison

I spent some time today looking into this. There are some issues with the wheels, but the majority of this problem is solved by increasing the mass of the wheels.

I just tried reverting everything from massScale="0" to "1" and it still is bouncing around. Thanks for the bug report. We'll look into it.

I noticed you are using a lot of massScale="0", which can cause some instability in crafts as it is inherently non-physical. Do you notice issues if massScale is not zeroed out?
