Commercial aircraft tires are charged with nitrogen because it is inert.

Not so dull when you think of taxi-ing on the runway, ready to take off - complete with 350+ passengers, crew, fuel and accompanying luggage.

Give me dull and inert anytime, reminds me of a few men I know; especially those that can drive!!!

Between me and my wife the number of accidents we have had as a collective is 3 the number I have had is 0

Sex really isn't a defining factor of 'good driving'.

I actually think my driving is getting worse the longer i drive i'm now coming up to 25 and am starting to drive like a pr1ck.

Yeah that's about right 18-25 drive like an idiot, 25-40 drive like a pr1ck, 40-60 settle down and drive responsibly, 60+ it's all downhill from here (back to driving like an idiot in a different way).

I missed this stage!!!

Do note that I made this up on the spur of the moment the numbers are pure guesses.

I would have never guessed

By the by in england a Nissan Micra

I now drive a 2000 pontiac sunfire before that a 2000 pontiac sunfire c/w AC (the mrs wrote it off) before that a 1990 Lumina (chevie i think).

It's not anecdotal. In the UK women can get significantly lower premiums on the basis of lower claim rates for women in general. There are several firms that specialize in the area (Diamond, Sheila's Wheels etc). There are also firms that specialise in the grey market (oldies also make less claims). I think it would be hard to prove a discrimination case against an insurer on the basis that they were unreasonably discriminating, after all that's how insurers make their money by calculating the risks of different groups (usually so they can avoid the bad risks, such as young men).

The law in Canada isn't that unreasonable sexual discrimination isn't allowed but that sexual discrimination isn't allowed. If you except insurers from the law on the grounds of rationality then there's also a case for exempting them from the law against racial discrimination, we can't have that.

something in that.

The point here though is Insurers identify groups which could be by age or sex or any other factor. Then from analysis of claims data they can predict risk. Those groups with higher risks pay higher premiums. The law does not come into this as risk factoring is legitimate practice.

They cannot lawfully use sex or race as a group identifier. They do currently use age, presumably because people old enough to fund a legal challenge to the practise have no incentive to do so. They can't use sexual orientation either, otherwise I suppose the Subaru Legacy would attract very low premiums.

Seems a bit silly. Why penalize women for men's bad driving?

The women may be more careful in the UK.
But due to a significant amount of cars being automatic, the very common sight of a women chatting away on a cell phone and consumption of coffee or food on the highway would suggest that a noticeable percentage are far from safe
The mum in a hurry is reason enough to avoid travel in peak school hours, and again a noticeable participant in low speed rear-end shunts
