A Segway is a two-wheeled, self-balancing personal transporter. Imagine a scooter that you stand on and it keeps you upright. It uses sensors and gyroscopes to maintain balance. It's like a futuristic chariot, but for sidewalks. It's different from a scooter because it doesn't require manual kicking; you lean to steer. While initially hyped as revolutionary, its popularity plateaued. Think of it as a niche mode of transportation mostly used by tourists and security guards.
