I find it shocking that something as simple as personal belongings would be a "lock in" to existing technology.
It's like saying "I prefer my horse, I can feed it grass off the side of the road, but you have to find some fancy petro-chemical station for your auto-mobile? Insane! My gas grows next to the road!"
I get it, but try to put yourself in the place of someone younger who doesn't make decisions like "I would never replace my car because I keep spare diapers there!"
>If "mobility" were so desirable, ZipCar would have taken off 10 years ago. The "mobility" market will be about the size of the taxi, bus, and train market.
This is very Bill Gates "no one would ever need more than ..." argument. Come on!!
ZipCar has literally nothing on the future of mobility.
You (and many people your age, conditioned from birth to place massive value on personal car ownership) may never move past that paradigm. You might go to your grave in 50 years a proud owner of a vehicle in an era where almost no one owns.
I think, instead of sagely predicting failure, maybe try creativity, use that entrepreneurial mindset to solve future challenges.
You want to keep spare diapers nearby? Why not have a secure storage module in the vehicle, lets say the trunk can be split into 2 or 4 secure storage modules.
You order an autonomous electric vehicle to your location, ETA 5 minutes. You hit the "bring my secure storage container to my location" option, restricting the available pool of cars to meet your need to those close to your container, at a small additional fee.
Boom, the "insolvable" problem of personal storage in a vehicle is solved by commoditizing the storage and use the AI vehicle to transport it where you need.
I'm sure you could come up with a better solution if you tried.
