From my memory voat was the only place that initially seemed like a possible reddit replacement. However any place that boast it has "free speech" and no moderation is bound to become overrun with bigots, which it obviously became infested with.
I think a lot of people are fed up with reddit for good this time. A few years ago I secured an invite to Tildes in the hopes it would be a replacement for reddit, but sadly it was just too desolated. Lemmy on the other hand has gained a lot of momentum that I think will keep on going after the blackout. I'm hopeful that the communities that have sprung up will continue to grow. While reddit won't go anywhere any time soon, I hope that enough people have fled for good this time.
Traffic giving away for emergency vehicles will hopefully in itself be of great help at reducing annoyances. Tough I'm a bit worried when they say “The citizens need to find a parking space and that will further drive up the importance of handling roads and traffic.”. I could see that becoming a problem if not implemented right and further congesting traffic. Them implementing seasons sound really interesting though!
