Get out of my nightmare, get into my car

Babysitting this weekend, and it will involve installing a car seat into the Mustang (is this even possible?!) and driving a kiddo like 45 minutes down the highway. Needless to say, I am TERRIFIED. And will probably drive about 30 mph with my hazard lights on. And sidebar: do three-year-olds like 80s music? Because I don't own the Frozen soundtrack. And don't really want to.
