A couple of reasons. First, you could compare a self driving car's safety against your own record. I've had a licence since 1988 and never had an accident. I want to compare against that standard.

I suspect there will come a day when the premiums are much lower for self driving cars but right now I suspect they'd be higher due to all the added self driving equipment you're insuring as well.
