The friction, risk, and uncertainty of rental cars sucks. Friction: pricing is unpredictable between and within vendors so you have to waste time comparison shopping on ad-laden sites to avoid getting screwed, taxes and fees and insurance costs and benefits are often opaque, and you have to somehow get to and from the rental office which can be far away (Enterprise's pickups sort of kind of help with this but need to be much more Uber-like), and you have to wait an indeterminate length of time in line (from 0 to 60+ minutes if you're unlucky during a rush) and then you sometimes have to trek a ways from the office to the actual car. Risk/uncertainty: your car may not exist (has happened to me often) or may stink, or be dirty, or somehow not what you were expecting, and the alternatives, when they exist, usually involve an argument and an upsell; and if you have an accident, the insurance paperwork is a nightmare even when you're 100% covered, unless you've paid for the expensive rental agency max coverage. Having your own car is predictable and low-risk, if expensive in other ways. But if your time has value, and you add the probability-weighted costs of not being able to leave for your trip on time, or go at all, or do it in a sub-standard car, renting can be pretty expensive too.
