no, its not based on driving experience , it is based on age and sex, insurance premiums are higher for under 25 male drivers regardless of whether they have just passed the test or been driving for six years, that is a fact.
next fact in Ireland, insurance premiums are higher for cars with larger engine size, regardless of whether the driver has been driving for 1, 2, 3, 4, 5 or six years or jut passed the test, small concessions as regards no claims are made to all drivers who have not had an accident for so many years,
Having an accident is not always reflective of a persons driving skill, but insurers work on the basis of making a profit so if they have to pay out, they penalise the customer unless he can categoricaaly prove it was the other drivers fault.
insurance companies clearly think that speed is a major cause of accidents , otherwise they would not be penalisingdrivers with powerful engines
