That sounds like a them problem—society won’t change any practices to accommodate these toys that are demonstrating how little value they bring every day.
You mean the same society that built thoroughfares, roads, stop lights, and laws for the benefit of transporting people and goods? Why wouldn't they modify the infrastructure to save a substantial fraction of the costs?
Transportation is literally the 2nd greatest household expense [1], and the cost is dominated by labor. I'm not sure how you could conclude that the potential for massive savings is a "toy".
Because if transportation decisions were driven by total cost to society, we would already have trains and transit. Instead, the costs are split among multiple entities, and weighed by planners and politicians against cost of new things, community preferences and personal preferences and commercial desire for profit.
Ableism at its finest. If these actually deliver on driverless cars it will be a boon to people who can’t drive. And that completely ignores the value in letting people work while they commute and the reduced loss of life from wrecks.
