Constraint vehicles going haywire when sitting in them

I have a pretty basic constraint setup for a vehicle system, four wheels connected by Springs and CylindricalConstraints.

It works pretty much fine, however I noticed that when I tried to scale down a vehicle it breaks it, and it goes crazy when you try to sit in it, as seen in the video.

I am struggling to understand what causes a vehicle to go haywire like this, perhaps others have had issues similar to this and know of a solution?

I am even more confused by the fact that for me at least, changing the scale of the vehicle is what triggers this to happen. When I initially set it up the car works completely fine and the glitch does not happen, it’s only when I adjust the scale
