This time the panel of drivers view a series of dramatic traffic incidents on UK motorways and roads across the globe. We see clips of tailgating terror and the serious errors made by cars exiting motorways.We witness a collision on the I-10 motorway in California when drivers were distracted by the remarkable sight of the launch of Elon Musk's Falcon 9 rocket. And we observe the chaos caused when a Mini driver tries to undertake on a dual carriageway near Poole, Dorset – with disastrous consequences. Plus, we reveal what can go wrong when driving in the rain, and witness the mayhem caused when lorries lose their loads unexpectedly.
