Searching for car insurance , I note that there is hardly any difference in price between - Comprehensive / TPFT / TPO cover .
Indeed in some cases TPFT / TPO cover is more expensive than Comprehensive cover .
A major cost for insurance companies is paying out for personal injury claims- for example if someone is badly injured and unable to work the payout can be millions. These payouts far exceed the cost of damage to a driver's car. Premiums for both TPF&T and Fully comp have to be sufficient to cover potential personal injury claims.
This explains why TPF&T premiums are similar to comprehensive costs but i'm not sure why for a given driver TPF&T would be dearer than Comprehensive.
