I am a caregiver that is out and about but does not use my car, I use public transit or walk with my large stroller up to 5km away. Everyone chose me because of my field trips. I don't feel comfortable driving them myself (I am a relatively new driver), but love the public transit in my city and the bus drivers are very friendly and accommodating to us. The kids love the bus ride more than the destination sometimes, and they take turns pushing the stop button, paying the fare, etc. So that's also an option, depending on where you live.
