Baby hates the car!

Kay • After four miscarriages, I'm enjoying my perfect little rainbow girl and now her perfect brother.
My daughter is pretty relaxed typically but in the last two weeks she's decided that she hates the car. I know, usually kids love the car (and I don't care to hear about your kid who does love the car!) 
She will scream from point A to point B and occasionally fall asleep for a few minutes and then start screaming when she wakes up. When we get to wherever we are going, I usually take her out of the car seat and put her in the carrier (although we've gone out to eat and left her in the car seat and she's been fine), so it seems to be only in the car when she can't see us.
I'm thinking of printing a picture of my husband and I to tape to the back seat so she can see us. Any other suggestions? Anyone else been through this?
