Need some help. Car clipping issues

Currently running DX11, with 100+ mods hence the Gavril GPV Clipping through the other cars, I've noticed the clipping issue with other vanilla cars as well, and yes the simplified collision physics is off, although after turning it off and on that seems to work, until I resest the cars or mission/scenario. Clipping mostly happens when I'm too far from the npc cars, and they tend to clip through each other, specially races. But when I get about 1-3 metres close they start to collide again and it makes the cars stuck to each other, I'm wondering if this is caused by certain mods or some modded vehicles, or is this a game bug?
