Still don't see the logic in how I can be a greater risk than anyone else for having my car driven into when parked or my bike stolen, or your wife for having her accidents. Both firsts in over 40 years for me but obviously not taken account in their "statistical ratings". Surely it is a random thing or do we all have an imaginary "fate" rating? Also, so what, I paid for the insurance in good faith or why have it anyway? This is something we now seem to take for granted, if you make a claim your insurance will go up next time. But why should it, where did that logic originate anyway? Just adds to the "scare" factor in making a justified claim imo.
I haven't lost my NCB (another illogical piece of insurance jargon) as it was protected on both occasions so still have "maximum years" in theory, hate to think what the quote would have been otherwise.
