Last October, when Yamaha showed off its Tesseract concept, we had trouble deciding how to classify the vehicle other than as extremely awesome. We are left scratching our heads yet again as Swiss automobile and motorcycle customizing company Sbarro unleashes its Pendolauto concept. Like the Tesseract, the Pendolauto leans into turns like a motorcycle would, yet features four wheels, like a car or a quad. With most of the excitement of a motorcycle, the machine would certainly be a blast to ride, but perhaps a bit more stable due to the addition of the two extra contact patches. Piaggio has seen a great deal of success with its MP3 scooter, but that machine features three wheels and is classified as a motorcycle. Because the Tesseract and Pendolauto have four wheels, nothing quite like them will be available in the U.S. any time soon. Unfortunately, the powers-that-be have yet to understand that a machine like the Pendolauto can offer similar benefits as motorcycles while perhaps adding a few degrees of safety.
