Friend of mine used to volunteer for the local chapter of a well-known national non-profit. He tried to explain all the technical benefits of setting up a website, yada yada. The board didn't care and were bored.
He finally set up a small demo on his own. Just a few screens. Ran a small test. Presented static screenshots, along with charts and stats on viewership and engagements. Had mockups of donation pages, volunteer signup screens, newsletters, etc. That was when people saw the value and got interested.
Nobody cares about decentralized social networks, the technology, or how terrible the other outlets are. For a municipality, you may want to focus on maintaining multiple channels of communications and ways to reach and engage the most users. You could then fold the fediverse into it as one more channel. Something they should keep an eye on. They'll need a way to post the same content to all those channels with the least effort. Something easy that a trained intern or clerk can do.
Guarantee there will be questions of cost of setup, maintenance, and risks. May want to have some answers and slides ready.
1000 charge cycles. If you charge twice a week, that's 500 weeks or a little less than 10 years. There's no mention of degradation over time.
But back-of-the-napkin, it means for this to be cost-effective, they may want to come up with some sort of replaceable or battery swap system. Not sure anyone will want to buy a vehicle that needs a massive battery retrofit every 8-10 years.
