Imagine if you owned 10 rental properties, were a plumber, an electrician, a basketball coach or had almost any job other than something in the tech industry. You would use your truck/van/large SUV for hauling trash, wire, sports equipment, etc.
You would laugh at the idea of selling your primary transport and using an uber/lyft every day to transport all your equipment. Every time one shows up or drops off, remove and replace all your tools/gear. The wear and tear on these vehicles is greater than a small commuter.
Just because you rented a truck once to move gardening supplies makes you anomalous. Most people who want to do that kind of work/hobby own a vehicle that allows them to transport these things with ease.
We haven't even gotten into the aspect of children. Imagine remove/replace every day on a child car seat from a rental.
