Is it a good idea to buy insurance from the car rental companies?

Insurance products sold by vehicle rental firms are not a good deal. Aside from being overpriced, they have a lot of exclusions hidden in the fine print. Rental companies also exaggerate the cost of repairs and find imaginary damages. What many renters don’t know is that rental firms do not profit off their vehicles but earn money from other things they can bill to the customers, such as insurance. Insurance scams are therefore a common source of revenue in this industry.
