I believe to what you said in the car. It depend on each individual but for me I think everyday innovation comes in our way. Great minds are creating better things for everything running as fast as bullet.
Everytime, I am browsing my social media account almost everyweek I see innovative things and the old things become obsolete as time passing by. So not owning a car and renting for a while maybe a good idea because you will never know what future technology would bring, maybe we can see a car that runs in the ethereum very soon.
