I live in a highly walkable/bikeable/transit-able area and rarely use my car (perhaps 3 times/month during the summer, a bit more often during the winter). The reason I’m keeping it is because most of those trips involve my older dog and she can’t travel via bus or in most carshare type vehicles and services. I anticipate selling the car when I no longer have my dog. My car is 14 years old, has been paid off forever, and is in good shape overall.
A friend who lives nearby floated the idea of using my car as a carshare with him and his wife. They've been car-free for years but would like to use my car for backpacking trips, trips to the homebrew shop, etc. I like the idea of sharing resources with neighbors and am on board with that aspect of it but could use some advice about how to figure out the risks involved. For example, what if they get in a crash and injure someone else or themselves, how would that be handled? I want to reduce liability on myself as much as possible. Also, I’m struggling with figuring out how much to charge. I initially thought about charging on a per mile basis to account for the extra wear and tear on the vehicle. Any ideas about how to account for this?
Thanks for any advice.
