As a general to comment on the thread I do understand people get pissed a the level of premiums and can always point to supposed inconsistencies. I'm on the other end of the scale and insure many cars for as little as £100 per annum fully comp (that's a 6 litre £10,000 value Jeep on a classic US car policy). I've had 1 accident in the last 20 years, garage my cars, am getting older and shop around

I don't want to carry any loading for young people, higher risk , etc. My daughter pays her own £700 premium and imho is a great driver but a risk....She's been hit once already and ended up a knock for knock claim :thumbsdown:
I happen to have been in the credit card and lending business for decades and pioneered credit scoring models in many companies. Insurers use similar models to calculate risk. One of the least understood factors is correlation of risk factors.
You crash the premium goes up - easy to understand.
You get 3 points it goes up - harder to understand, but regardless of the oddities of speeding offences there is a higher propensity that a person caught speeding will result in a claim because on average they drive faster are less observant of cameras, aware of danger or something similar.
You're a single male aged 20 driving a high performance car - no score model needed - you're a risk (remember on average you will result in more claims)
So think like an insurer - reduce the risk and therefore premiums:
Don't get caught speeding
Reduce the agreed value of the car
Reduce the agreed mileage
Pay more excess because that means you believe in your own ability
Garage it or get it off the road, etc. so it doesn't get stolen
Shop around and don't let the clever algoriths take advantagfe of your laziness to shop around
