Los Angeles is notorious for its private car-based transportation.
The biggest disadvantage of the privately-owned car is the fact that it uses too many resources for too little effect. All that waste leads to a reasonable question:
“What if we were able to dissect a working car into working components which could be utilized according to given circumstances?”
Those components would concern the Engine, the Cabin & the Trunk. Contemporary cars do not offer the choice between those 3 components. Basically, you cannot have the one without the other. But it is possible that in the future LA people would be able to own only the Cabin and, through AI centrally controlled circulation, they could create a temporary assembly-unit, an ephemeral design, which would serve their “exact” needs on demand.
LA would then be able to invite its people and visitors to streets liberated from the old overflow of vehicles and ready to accommodate their “exact” needs, no more, no less.
