Two car manufacturers have said the answer to the world's urban transportation problems comes in the form of a two-wheeled electric vehicle.
Both General Motors, which owns Saab, and Segway, which develops green transportation, have said the way to tackle urban congestion and CO2 emissions is by using two-wheeled vehicles not four.
As a result the companies have announced they are working together to create a two-wheeled, two-seat electric vehicle, which will be fast, safe, inexpensive and a green alternative to the car.
The Personal Urban Mobility and Accessibility (PUMA) project aims to create vehicles that can communicate with each other to prevent crashes and regulate the flow of traffic in cities.
A prototype, which weighs just 300-pounds (136-kilograms), has been developed which runs on a lithium-ion battery and reaches speeds of up to 35 miles-per-hour and can travel for 35 miles (56 kilometres) on a single charge.
