Current rewritable drives, either rotating or solid-state, leave behind "ghosts" of what was previously written that would allow forensic experts to detect tampering. This write-once drive is just tweak on that. It also depends on trusting the drive manufacturer not to include a back door allowing a rewrite. It's not a bad idea but addresses something that's not a priority, it's not a panacea, and they're the sorta folk that might not commission something compliant in time. Dominion should get something compliant made and, if no one else does the same, they can demand an unhealthy amount of money as the unique supplier.

Autonomy is helpful for all transit scales. When I see an essentially empty bus go by, I shudder at the waste. Other times, I cannot use public transit because they stop running to avoid travelling below a reasonable capacity. More frequently, public transport cannot handle first and last mile because it's inefficient. Transport must handle all these problems and the solution is likely a mix of higher- and lower-capacity vehicles working together. A "car" may drive you to a be picked up by a "van" and, for longer trips or during rush hour, on to a "bus", and then, as you get close to your destination, back to a "van" and a "car". There may be less need for large transfer stations and instead they'll be distributed so dynamic inter-vehicle transfers can happen almost anywhere with minimum wait between dropoff and pickup.

The complexity of having all these vehicles work together so dynamically is beyond human capacity, hence the need for an integrated system with extensive autonomy. Yes, a human could and will drive some of these vehicle but the system will work far better with many, most, or nearly all of them being autonomous.

Yes, it's good to build to endure extreme weather events. However, we are more interconnected than many preppers want to accept. In this instance, this community will likely receive property insurance quotes that are very high because rates assume average claim costs. "Holistic prepping" makes things sustainable not only for oneself but for one's extended community
