Idiot on mobile phone (with kids in the back of the car) weaved out of Sainsbury's (Stratton St Margaret) at walking pace and then, being unable to drive with the phone in his right hand, edged out and completely blocked the Gablecross roundabout, getting abused and beeped by the driver of a silver Vauxhall Insignia who had the right of way.  Even then he didn't put down the phone.
