There are lots of good reasons distribution companies don't like cables in some situations (especially rural). Connecting new customers and network alterations is much more expensive, changing to a higher voltage is not possible, upgrading capacity requires a whole new cable which is more expensive than replacing the conductors, cables only last about 30-50 years. Finding and fixing a cable fault usually takes much longer than overhead (although there are probably less of them per mile). Without wild fires, I seriously doubt cables are more economic in rural areas.
