Perhaps it makes more sense with finance, I buy my cars outright or get a loan of some sort to cover a relatively small part of them so this hasn't occured to me. That is the ONLY situation in which I can see it makes sense, otherwise it is money for old rope unless you really think you are going to write it off after the 1st year. I would restate though that if you think you are protected against write-off in first year, double-check your policy wording for your fully comp insurance - many don't explicitly say they'll give you a new car.
