Roll the dice if you can't see the point of it! They're probably useless until you need them

I think in this case though, we are pushed into having it because the penalty charged is more than the cost, which is a very artificial playing field.
I object to it in that it has been setup to encourage customers to keep up the cover, which is what the insurance companies were arguing what was causing the problems, yet there doesn't seem to be anything that otherwise makes it an attractive proposition. You would hope that it would sell itself, but apparently not.
