Every time I see someone say "all cars will be rentals in the future" I think if all the people I know who have stuff kicking around in the trunk that they use occasionally but rarely. The automotive version of "every-day carry". Some of it's basic car maintenance stuff. Some of it's not.
And then I also think about the people I know whose passenger or back seat is a giant pile of trash because there's no easy-to-empty integrated place for trash and it all just ends up on the floor...
Also to quote this incredibly relevant point from fartaspoobutt [dead]: [1]
The car I really want is a network of fast, affordable, widely available public transit.
