What should determine your car insurance?

I agree, as a business your objective is to earn money, so ideally you'd want to know everything you can about a person before quoting a price.

If a new study was taken out that showed for example Japanese drivers are 20% less likely to write their car off, then companies would probably want to vary premiums based on race... Well if they could get away with it - of course there's regulations, and even then a lot of customers would be outraged and change to a less racist company.

I think a good system would be for any driver with a statistical high risk to initially pay a larger sum of money to the company than normal, but with a large percentage of that sum being a deposit. If you crash your car or cause an accident - you loose the deposit, or a percentage of it. However, if you haven't caused any damage you get the deposit back.

That way insurance companies could still earn money from young drivers without ass raping the sensible ones that are just unlucky to be in a high risk category. But of course, that will never happen.
