I have “set simulation physics false” binded to press key and I pressing the key repeatedly and car never freeze. See:

As a newbie I just want to make sure my bone structure is correct coming from blender.
Some tutorials I’ve seen have a body bone while others don;y. From what I understand it has to match the FGear bone structure. Is yours different?
try it with the red or blue car, it looks like it doesn’t apply to vehicles with custom collision, we’ll look for the cause.
you can see our sample skeleton in this video : https://youtu.be/04dP5mEKd-I?si=AJEBRlRYxKwE5VgM&t=125
Is it possible to look at the bp of sample vehicle that feature truck with trailer? Because I am having trouble changing the constraint location… is it because of FGear vehicle being the root?
Yes, blue car is possible to freeze by set physics simulation false.
@lazybitgames Every time I try to disable detect ground velocity ( for optimization) my editor crashes. Any idea what might cause this? It doesn’t seem to happen on the vehicle blueprints that came with the plugin.
So I should just delete the bone named “Body” in my pic?
So I tried both with the extra bone and without but still getting a wheel problem. Any ideas where I should start first?
delete the 4 wheel bones from skeleton tree in physics assets so you just have the root Bone only in the window where you generate the bodies ,i had same issue and thats what sorted it for me ,hope this helps as it did for me

That worked, the wheels are spinning but the car’s not moving. 
could be a number of things follow this to get basics down then i went with enhanced input https://www.youtube.com/watch?v=04dP5mEKd-I&t=126s&ab_channel=lazybitgames
are the front wheels moving the way you control them to through your selected input? theres also a animation BP tutorial aswell mate
I increased
the wheel radius from .25 to .4 but the wheels still seem to penetrate the ground and the car doesn’t move
0.35 seems to be a sweetspot for me but just try different values
what does the crash log say?
your videos doesn’t tell much, enable gizmos and use a simpler environment, just test it on a plane first.

The gizmo on the van switches off when I start recording
Can someone send me the engine input .ini file as i haven’t got access to the example project
What is the collision on that surface? Does it block for visibility? Try a convex wheel and see if you get collisions
