Because private insurance companies cannot compete with ICBC. They only get the scraps of peripheral insurance right now. The add-ons. They NEED to have higher rates from ICBC to allow them to compete for basic insurance too.
Gordon Campbell, (oh no, he's not going to blame Campbel again) has too many friends in the private sector, he needs to get the rates up to where the private insurers can get in on those profits too.
Once we all start complaining about ICBC rates he'll allow his private company buddies in to compete against ICBC, and they'll cherry pick all the best accident free drivers and leave us taxpayers with the bad ones.
