Is leaving your unpainted carbon road bike in sun a bad thing?

I noticed someone at work leaves his unpainted carbon road bike on the roof of his car about 3 times a week.

As someone is fanatical about keeping my stuff out of the sun, particularly my motorcycles, what is the damage to a frame over long-term exposure?

Long term, not healthy. Does it have a clear coat of some kind? That will help a little but I still wouldn't be leaving it on the roof of the car all day multiple days a week.

Actually, the story is that he had stopped to let a family of pigs cross the road. When he started back up, the mama got mad and started chasing him. He glanced back to see where she was and ran into a ditch and sat heavy on the toptube.
So his balls made that hole? Either crappy carbon or balls of steel.
