Niche mod
Override car mass to be initial (without loot inside). If you have too much loot inside vehicle, bullet's car physics gets wonky.
Its advisable to wait 1-2 seconds after putting loot until car mass gets overwritten by the mod. Because there a chance you annihilate your car with unexpected physics.
Recommended mods to go with this
Container Capacity Limit Bypass (CCLB)
Unlocked Backpacks / Bags / Containers

Also if you encounter problems with car physics - you probably have to disable that mod.
