An environmentally-friendly Swedish start-up is attempting to change the nature of city mobility. Bzzt! as it’s known is a city centre taxi service, which uses app-hailed, three-wheeled electric pods to take people to their intended destinations. Student Frida Longnell needs to make a journey through Gothenburg’s busy city centre. But rather than taking a bus, or flagging a traditional taxi, she’s using a fledgling start-up to negotiate the traffic-filled streets of Sweden’s second largest city. Using a dedicated smartphone app, she’s hailing a Bzzt! pod taxi, a battery-powered, three-wheeled, yellow passenger vehicle, to get to her intended destination.
