What counts as an unnecessary car ride for you? If I'm going to the grocery store and there's someone else to watch my toddler, I don't need to take her with me, but I think the bit of stimulation of getting out of the house and seeing a new place, new experience, and new people has a benefit that outweighs the almost inconsequential odds of a major car accident as I drive there and back on roads with a speed limit of 35 MPH.
