It's not worth it. Unless you're a die hard PETA member, then you'd destroy everything you've got for that squirrel running across the street. I'm the same way, I don't swerve for something unless it's bigger than a cat or something that could do damage, and only will if I'm in an area that would be safe to do so. Better to hit something and mess up my bumper than swerve off the freeway and smash into a ditch and total the car, or worse.
