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

No, you need more urgency in your tone. And some scattershot votes from sockpuppets.

But don't worry, with practice you'll get better at it!

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.)

If we're very lucky in ten years most new cars sold will be electric. That is very different from most cars on the road being electric. It is also unlikely that the electric grid will be carbon free in ten years.

I've heard we have no idea how to recycle li-ion batteries, so the whole electric car thing is rather tenuous.

That's not true, electric vehicle batteries will have large quantities of valuable materials worth recycling, and companies are already working on this. https://spectrum.ieee.org/amp/lithiumion-battery-recycling-f...

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.
