Mystery of scratches on my car

Guys I hope someone can help me or propose a solution.

I take the greatest care in looking after my car, and because I wash my car every weekend (using proper tools and products) I know my car inside and out.
I am the only driver, and by taking proper precaution Ive only had minor scratches on my previous cars.

Ive recently noticed scratches on the exterior of my car. The last 2 weeks I seem to notice a new one every day, and its leaving me frustrated and just plain angry because I dont know where they are coming from?!?!?

I park my car in a garage at night, and in a office park during the day, I am pretty sure that my car is not being vandalized at these locations. During my commute I cant recall hitting objects like stones, or whatever. WTF is going on?! I am completely stumped?!

Im seeing random scratches in all shapes and forms, ranging from 5cm to 15cm long on every body panel imaginable, roof, bonnet, boot, sides - everywhere!

I need to get to the bottom of this, any advice or recommendations will be appreciated. If this persists my car will look like taxi in 6 months!
