How Google's autonomous car navigates city streets

Google's self-driving car has been on the road for five years now, at various levels of autonomy. From the ease and relative serenity of California's arrow-straight highways, the car drove hundreds of thousands of miles with a greater level of concentration and mastery than the wandering attention spans of humans could accomplish. In 2012, Google shifted from the freeways to the cities, navigating a far more convoluted set of challenges: the slow-speed chaos that comes with any city, any suburb, any place with people and cars in it.

Peugeot BB1 concept

Peugeot BB1 concept was one of the more interesting surprises of the 2009 Frankfurt motor show. Capable of accommodating four people in a package only 2.5 meters long, the all-electric BB1 concept seeks to reinvent the car in every respect: architecture, style, interior design, driveability and connectivity, bringing the environment very much to the fore. Conveying values of freedom and optimism, and even 'altruism', the BB1 concept offers the promise of a new driving experience, wrapped in an altogether fresh and intriguing package.

Ford Vertrek concept

Ford used the 2011 Detroit auto show to unveil its Vertrek concept. The compact SUV is billed as potentially leading the industry in both design and fuel efficiency. The Vertrek is the latest evolution of the Kinetic design language that debuted on the Iosis concept, which subsequently evolved into the current generation Mondeo.
