Well.... if he wakes up one morning in Poughkeepsie he won't be doing it again.

I guess I'd be tempted to take him for a ride to a nice rural area and then open the tailgate.

Found an article in "ask yahoo". Here is the link for whatever it is worth: http://ask.yahoo.com/20000505.html

I've got an old farmhouse. Place is loaded with bats. They get in from the smallest spaces. I keep a long handled butterfly net on the back porch now for bat removal. Mostly it's in the spring and early summer when the young ones are moving out on their own and get confused. Once they have a clue they stay out in the old attached barn.

You could put a few bat houses out back someplace so they find a more comfy place to stay other than your car.

Like the old bat in the farmhouse :) says..'bats get confused'..I get one or two a week, 'sleeping over' up in my breezeway, between the house and garage.
I've two bat houses posted in trees. no bats, tho the local swallows seem to like the houses fine. The bats seem to prefer my neighbors abandoned barn better.
I also have a Subaru Forrester, no bats in the car yet. Maybe in a couple of years when Subaru finally comes out with the quieter hybrid version i'm waiting for :)
What i'm curious about...how do they get in the car in the first place?? Do you not shut the car doors upon exiting or something??

En route from MA to WNY during a hot August day, I a bat trapped in my CRV's ventilation system. Occasionally screeching and flapping its wings for several hundred miles (2-hours), it remained there until I recognized and solved the problem by removing the cabin air filter in my glove box. How and when the bat got inside my car's ventilation sytem, I have no idea. True story.

I'd roll up the windows.

Suehn we keep tennis rackets at the ready. One/two a year is not uncommon. We also get mice in the walls..life in rural areas!!
