I think it is safe to say that almost everyone remembers the Segway Scooter and how many different reactions it brought from different people. Segway has since remained under the radar for the most part, until just recently when they and GM partnered up to make a small city transport dubbed PUMA.
PUMA stands for Personal Urban Mobility and Accessibility and is designed for city dwellers who prefer not to use crowded streets. It will carry at least 2 passengers, with the ability to carry more depending on future seating layouts and boasts a top speed of 35mph.
Much like a Segway, the PUMA will move around the city on only two wheels. The same stabilization system that is currently on Segway's scooter has been adapted for use on the PUMA. It also uses a Smart Battery Management System to keep the Lithium-Ion Battery Packs providing an even supply of energy to the electric motors.
According to GM, PUMA is designed to move people around a city "quickly, safely, quietly and cleanly." The only real challenge I can foresee is trying to navigate busy sidewalks, which can be more frustrating than driving in bumper-to-bumper traffic. No word on if or when PUMA will see full scale production as of yet.
