Utility companies are deliberately regional monopolies, without the threat of competition there's no incentive to do better. That's presumably reflected in but not limited to the quality of their web sites.
investigations subsequently determined that PG&E had falsified reports, and failed to conduct testing that was required by law.

I recall the San Bruno gas explosion[0] you're referring to. It happened at a time when I regularly drove down that leg of Skyline to access Pacifica and Ocean Beach coming from south bay via the peninsula/280.
We clearly need better solutions for how such utilities are delivered and their businesses operated. Though in the case of residential gas lines, we should probably just stop the practice, especially in seismically active regions like the bay area...
