Q.What is white spray from fruitless mulberry tree
The canopy of our fruitless mulberry extends over our driveway. This year it’s been spraying a white spray all over our car parked there. On the side facing the mulberry. What is this? Pollen?

This is likely Honeydew, which is the residue or secretions of insects.
I would inspect the tree more closely and treat with Neem Oil.
Here are some links with more information.
