Vibrations on Unity 2018

A large container suspended with two wheels:

Hello Menzagitat,

We've also experienced physics problems with the car in tutorial in Unity 2018, so we must fix it before releasing the next Update. Could you please upload this save, so we can tune the settings according to it? Thanks.

Hi Martin,
Here is the same construction in a new smaller save: save_766.zip
Additionally I just noticed that in the old unity I can drive the "vehicle" but in the engine version: 2018.1.7f1 I cannot.
If I remove the large container, movement is possible.

I checked my old measurements and I see no torque or suspension strength regressions:

• the small wheel can still lift 13.5 small armor blocks like before
• the small suspension on "soft" level enters in limitation like before on 22-23 armor blocks, in my specific setup

Most likely the friction was increased in Unity 2018.

I have nearly an identical issue in Version 0.9.2.2.23365 with Nvidia 750Ti with Ubuntu 16.04.5 (Linux 2 4.4.0-116-generic #140-Ubuntu SMP x86_64 x86_64 x86_64 GNU/Linux). While in build-mode my (red) aircraft is moving around on the flight-deck. It starts moving when a block was placed and wanting to add another block. The other two aircraft are not moving around.
