When Uncle Cosmo buys himself a motorbike and gives Mrs Armitage his boring old car, it soon becomes obvious that her driving skills leave a lot to be desired. Mrs Armitage and Breakspear cause havoc bumping into bollards, bedsteads, lorries, a crane and bedoinging over some extremely uneven roads. As the bumper, the doors, the mudguard and even the roof disappear along the way, the car is transformed into a mean machine and Mrs Armitage becomes Queen of the Road!
