According to the AA, the average car insurance for 17-22 year olds on Oct 2011 was £2342.
The idea is to create a car insurance business which has a flat rate yearly insurance fee of only £600 for under 23 year olds with 1.4 liter engine car and under.
First year get 500,000 customers at £600 each. That's 300 million. 5% of them make a claim with average cost £5000, that's 25,000 times 5000 which is 125 million. Plus another 10 million for that year for misc fees and total costs are 130 million. You've made 170 million. Close the business down after the first year and go buy your own island somewhere?
If someone could give a US perspective on it, that would be good too.
