I really wish there was a cost-effective way to rent some of these low-usage, but high-carbon items like cars. I really don't want to own a car. I barely use it because WFH + public transport + company shuttle handles most of my day-to-day. However, it is difficult to do some outdoor sports in the US without one (e.g. rock climbing, mountain biking, skiing). I have a Subaru in my garage on a trickle charger to keep the battery fresh only for these kinds of things. I wish I could avoid having to insure, register, and worry about this stupid investment, not to mention the guilt from having this barely-used thing expanding my carbon footprint. However, the math on renting a car every weekend that has all-wheel drive still just doesn't work out, not to mention the hassle of retrieving and returning it. I don't like the "you will own nothing and be happy" way things are going, but I could definitely do that with a car if the economics wouldn't be so rapacious.
