Dramatic footage has emerged from China of a car trying to change lanes on a motorway when there's not much room and ending up flipping over onto its roof. br br The dash cam video, filmed in Dongguan, Guangdong Province last Saturday, shows a blue Volkswagen changing lanes from left to right, but the car behind, which appears to be trying to stop the Volkswagen from changing lanes, speeds up narrowing the gap.br br As a result, the Volkswagen flips onto its roof, a slides along the road, causing sparks.
