Segway unveiling (2001)
Dean Kamen unveiled the Segway personal transporter, promising it would transform cities and replace cars. The device topped out at 12.5 mph and was hyped as revolutionary before it ever shipped.
Sales were modest, and the Segway became a niche product for police patrols, warehouse workers, and guided tours.
It never replaced cars or reshaped cities. The company was sold multiple times and eventually ceased production in 2020.
Like the Roadster's flying claims, the Segway's promises outstripped what regulators and infrastructure would allow. The hype around a new transport mode ran into the slower reality of rules and practical limits.
