Flaming exhaust

Thermal imaging makes it easy to see hot gases and this is clearly visible in part of the video in this BBC new story.

A stolen car is shown driving along a slip road on the M6 motorway, turning around to go back up the slip road (the wrong way) to avoid a trap and then turning back onto the motorway at speed. The exhaust gases from the car can clearly be seen as it speeds away. The wheels can also be seen 'white' (ie hot) and there are tails behind the car which could be either camera lag or heat left on the road by the tyres.
