Summary
Highlights
This segment explores the consequences if humans could move with the speed and agility of a car. It suggests that catching thieves would become nearly impossible, animals might flee the planet, pizza delivery would be immediate, villains would escape easily, and gas stations would see continuous refills. Also, roads might be lined with abandoned human "cars".
This part considers the effects of mobile trees. Footpaths and roads would become crowded, necessitating separate roads for trees. Forests would unpredictably shift, making weather forecasting impossible. Picking fruits would become a chase, birds would be confused, and wood prices would skyrocket as chopping down trees becomes difficult. Property values in previously desirable locations might plummet.
This section delves into the implications of a sudden doubling in human height. Basketball would become too easy, leading to empty stadiums. Entering homes would be difficult, requiring doors to be broken. Humans would rival giraffes in height, and mountain climbing would take half the time, delighting trekkers. Climbing buildings would be easier for thieves, but getting in and out of cars would become a major challenge, making roofless cars popular.
