Black patches coming while moving cars

Make sure they aren't VW's as they have been lying about their emissions.

 

On a more serious note, the lines are from where the car has cast a "shadow" during the GI calculation phase. Without seeing your settings, it's kind of hard to diagnose but I'd be willing to guess that you have calculated for a static scene and not one with moving objects.

 

Read the manual.

yep you would ideally render those seperately as single frame BF/LC and comp with the baked main plate

or do single frame BF/LC for the whole thing
