Prediction text

In cities people mostly won't own cars once autonomy mainstream (subscription model). | they mostly won't own cars at least in cities right in rural areas I think we'll see car ownership maintained for a long time but car ownership is an artifact of low utilization economics once you have autonomy converting the car from a consumer product to a service layer essentially it becomes a subscription model

No downstream cascades — this prediction is a leaf in the dependency graph.

What if this resolves?

Clamp this prediction TRUE or FALSE and run a counterfactual Gibbs sample. Surfaces the predictions whose marginals shift most under that assumption.
