The A30 highway runs deep into the South-West of England - from Exeter in the county of Devon to Penzance in the narrow peninsular of Cornwall. On certain dates in the calendar routes like this, near the Cornish town of Bodmin, England, come to a standstill from the huge volume of cars and private vehicles, all heading down to costal resorts and better weather. We see here a huge tailback of traffic that is queueing along one side of the British dual-carriageway (two lanes in each direction) from close-up to the distance down and up a natural hill in this undulating landscape. The cars have edged forward are nose to tail for hours in summer heatwave and tempers fray, children arguing in the back and an otherwise relaxed holiday mood suddenly goes bad.
