What can I do about bird poo on my car?

I basically have one specific carspot in front of my home and the bird poo has been unbearable on my car, it sits right under a tree.

On rare occasion, I have access to another carspot 10m away, no bird poo so I'm assuming it's the tree that the birds like to chill on.

I asked my local council to trim the branches overhanging the street parking but they said no so what can I do?
