On National Drive it Day 2009 Penny was distressed by a loud bang while negotiating a roundabout. She slowly rolled to the nearest exit and into a layby.  She was 40 miles from home and feeling so alone.
My first reaction was that she had a puncture, but when I inspected all five of her wheels their tyres were still pumped up.

I climbed in and turned the ignition on and saw that the warning light was very feeble. Aha - a loose connectio!? Start at the battery and work along from there. So I climbed out and lifted the driver's seat, opened the flap in the carpet and removed the floorboard covering the battey box.

The problem was immediately obvious - see the picture and guess what had happened.

I shouldn't have laughed when this turned up for a modern car at the starting point of our drive

So it wasn't so much a Drive it Day as Piggie Back Home...
