Problem with leaves

I’m having a problem with the Leaves. I wanted to make the animation of the car dragging some of the leaves, and then blow them off tires. Instead, they just “explode”, and some of the leaves are falling below the floor. Tried solidifying it, but with no success.
What causes this?

FYI: Ground Rigid Body Type is set to Passive, with Collision Margin turned on (0.4m), Leaves to Active and their mass set to 0.1. Applied Rigid Body settings from Active Object to all in Leaves Collecion, and there’s no wind force field.
