At this point anything short of mass murdering the world's population is climate arson. Am I doing this correctly?

I think the counterpoint is that if in ten years most cars are electric, then that is not really a fair characterization. If electric cars and buses and trucks remain the most prevalent form of transit, then roads will continue to be very important, and that includes highways. There are plenty of safety projects that aren’t really about expansion, but about repairing, maintaining, and making better. (Or in this case, to get cars hidden away so they aren’t noisy and distracting in a historic site.)

(Aside, I also don’t like highways in cities.)

Replace highways with high speed rail and you run into the same problems.

The Japanese when they built their shinkansen demolished countless old temples and ran straight through beautiful nature.
