Some years ago in a busy part of London a car shot out of a side street and drove into me doing some damage. the car was being driven by a young woman. I was driving my DH's company car, which I was insued to drive. We did the usual eschange of details.
A day later the woman'ss hsuband rang and asked me if I would put his name down as driver in the incident, not his wife's. It seems her car was out of action and she borrowed her husbands car, which she wasn't insured to drive, to make a very short journey to collect something. Unfortunately she had an accident.
I understood their problem, but said'no' very firmly. It made no difference to me, nor my insurance claim, and I had some sympathy for the mess they were in, but I was driving a car that was not mine, but had permission to drive and even if I had been tempted, if I was found out, my DH's employer might well kick up a fuss and that could have affected DH's job.
