I think once we have automated cars people in major cities will stop owning cars. Membership to a "club" makes a ton more sense if you can call up a car on an app and it drives itself o your location.
The tube runs every few minutes on popular lines, and don't suffer from congestion (when there isn't problems on the line), so they're acceptable. Trains running on a timetable less so (they make you pay much more attention to the time, and they're frequently delayed and increasingly often cancelled), while buses just feel like a massive waste of time.
In addition to the usual stuff you'd find in a kit, I threw in a four-pack of single-serve Krazy Glue (cyanoacrylate superglue), which is useful for controlling bleeding (a spray might even be nicer). Since I live in a climate that sees actual winters, I also included a pair of mylar emergency blankets (they also make a "sleeping bag" style), and I of course keep the usual extra set of boots/gloves/hat in the trunk during winter as well (totally standard around here).
I'd be interested to hear any other "unorthodox" additions to the usual kit, if anyone has suggestions.
The original list was mostly shareable items, but there's a lot of non-shareable items in my trunk at the moment.
We don't think about handicapped people whose cars carry medication and equipment for them.
We don't think about carrying stuff like nail clippers, stain sticks tampons in the car, either. So we'll waste more money without persistent access to this infrequently-used items.
We don't think about occupational vehicles like plumbers' and electricians. With fewer ICE vehicles on the road, their vehicle maintenance will be more expensive and our maintenance and construction bills will increase.
Not that I'm arguing against car clubs, etc. I'm trying to validate your line of thought.
e-bikes are starting to get really good, much cheaper and usually don't require anything like the regulatory approvals, driver licencing or running costs cars do.
I can certainly imagine myself using a hypothetical autonomous car club augmented with an e-bike for shorter ad-hoc journeys ("crap I'm out of milk" etc) very happily.
He, like most people, would not consider himself a cyclist and as such is less willing to put up with the post exercise issues of using a bike as a primary mode of transport. I'm a keen cyclist and am happy to put up with the faff of a change of clothes etc but I can see how it's off putting for most people.
Also, rain.
If the smoke alarm goes off the car pulls over and stops at the side of the road.
The rental company will already knows who in the car at any one time (or at least who has rented it) and they can just issue a massive cleaning fine.
Like setting off an airline toilet smoke detector.
In the situation you propose, you have would-be car owners who now share a car. That eliminates the pollution involved in the manufacturing of one car from the story. And yes, if the car had to make back and forth trips from a central location, that would be inefficient. But I think the idea is to have a network of shared infrastructure (similar to uber), so that if someone needs a car, they can have access to the closest available one.
Will you agree for example to be billed more for your assurance company because one of the co-proprietaries of your car is a bad driver?
And there is also the real use time, ie: you buy a car that is crashed each month when used by other guys and must remain in boxes to be repaired four months/year.
The idea that "everybody will want to share their car with strangers" is probably just this, a marketing desire IMHO. Bad drivers will want to share the car for sure, but a lot of common people would probably frown at the idea.
