Spiders spiders everywhere

I'm not sure why, but my car seems to be the local hangout for the spiders of the complex with acrophobia. (Our large window appears to be the place for a rather large spider to do his spidery deeds (outside, of course)). I've had several rather large spider webs on the passenger side of my car for several mornings now. I'm not sure where the spider is, or where he goes during the day, but I'd like him to kindly knock off on our vehicles. Thanks.
