I get what you're saying, but there is a measurable quality of life increase over an A to B gas-powered car.
* No oil changes
* Charge at home, wake up every morning to a "full tank" for a lot less than it'd cost to fill up with gas
* No gas station fill-ups
* Autopilot is huge for quality of life on highways and in bumper-to-bumper traffic
* I keep the valet key card in my wallet, but there's no physical key that you need to keep with you. My car key was the last one I really needed, so I no longer carry physical keys
* The car has an API, so you can use it to automate various actions (like to start the HVAC system if the car is at work and it's 4:30pm on a weekday). With my normal schedule, the car is already pre-warmed/cooled any time I get in it
* Built-in dashcam includes side cameras, and sentry mode
* Summon, and (soon) enhanced summon
None of that helps if you're driving a loaner while you're waiting for parts, but it's tough to quantitatively measure the impact of just having things like this. And I've got more faith in Tesla to improve logistics in parts sourcing than traditional automakers becoming more like Tesla.
