>These days I rent far more often, and even being part of elite programs and being very experienced with the process it is still far more of a hassle than simply approaching a car you’ve booked online, tapping your RFID card and driving away.

I don't have a car right now... and while I haven't rented a car lately, (I'm willing to pay extra for uber/lyft as it means I don't have to drive or deal with parking) I do pretty regularly rent a uhaul van, as the on demand hauling solutions are less convenient and/or more expensive, in my opinion.

The uhaul process is app-based and can be done at the last minute with your cellphone. They do want a cellphone photo of you and of your license, which is then verified quite slowly, but I don't have to personally interact with any humans to get my uhaul van, and it's usually pretty quick.
