The way fixed costs work few people drive enough to make owning two cars for different purposes worth it. The big SUV might be only needed a few times a year, but it is cheaper to pay for it all year long than to also pay for a small car. Rental cars are expensive enough that they are out.

For a while I did make a tiny car and a SUV work, but I had to drive ~100 miles a day for work and even then it just barely worked out.
