This is true
I remember checking my policy renewal one year and seeing an ex still listed as a named driver. Wanting to break all links with my past life (and possibly save some money), I phoned to get her name removed, only to be told it was cheaper to leave her on, despite her being responsible for the only "at fault" claim I've ever had to make. So, for a couple of years, my ex could still legally drive my car, though she never knew this.

The explanation I was given was that if you have another listed driver you might share the driving if one of you is tired, so are then less likely to have an accident. Presumably they'd have to be over 25 to lower your premium rather than raise it, and there may be some advantage to the extra driver being a woman, though it may also work adding a male to a female's policy.

By the way, despite often being able to get lower insurance premiums, women aren't necessarily better drivers. It's just that on average they drive fewer miles each year, and on average their journeys are at lower speeds, so on average their insurance claims are lower. That's what's important to the insurance company when giving a quote. Though feel free to add any anecdotal "men drive like nutters"/"women can't park" comments below.

Women are better
at defensive driving than men IMO.

However, they're far more inconsiderate. In my experience they hardly ever let me out of side roads or stop to let me turn right in front of them down a side road. It's not like I drive a BMW or anything. And if I let a woman driver out of a side-road etc, it's only in about 1/10 occasions where I get any form of aknowledgement, compared to say 8/10 for men.

And I've never known a taxi driver to not let me out of a side-road when the traffic's bad.

My mum
reports exactly the same thing. And she always lets people out.
