A worker makes auto parts on a machine inside a workshop in Faridabad, India, December 24, 2015. Car makers such as Maruti Suzuki India and Hyundai Motor see huge growth in India, set to become the world's third-largest auto market by 2020 as millions buy their first new car. Price tags can be as low as $3,000 for a new Tata Motors Nano mini-car. India is also becoming a low-cost export hub for global car makers such as General Motors and Ford Motor. As the sector expands, some of the work is sub-contracted out to small factories operating on paper-thin margins, where poor contract workers often have little or no access to safety equipment or health benefits.

Reuters photographers have worked not only to capture the thrills and spills on the roads and mountain passes. They have also shot a set of pictures showing their own quirky view from behind the scenes as they travelled through the Netherlands, Belgium and France. (Photo by Eric Gaillard/Reuters)
