If you drive an ICE that much you could be saving money vs renting a car when you need one. I've done the math, rental cars are expensive. Between the per day and per mile charges it doesn't take long to make up the cost of a cheap car. (if you insist on a new car of course that is much more expensive than a 10 year old car) I keep wanting to get rid of my truck that I only fill about 4x/year, but it turns out it is hard to rent a truck, as opposed to a truck shaped car. (I have found ways to do this, but those trucks are even more expensive than a car and they are out of the way)
