I wonder if you could calculate that. I thought that on a level area, the horizon is about 6 miles out (or is it 12?) based on that, could you calculate the size of the world based on the height of mount doom and the distance it would be?

I challenge you to try to live without a car anywhere outside of the NE. Cities just aren’t built for it and you can’t just redesign them overnight. Take the Texas Triangle for example, 21 million people and it’s extremely sprawling. Bus service in a lot of places are lacking and will take you 40-60 minutes at a minimum. You just plain can’t survive in a lot of places. So what will raising car prices 25% do except put much more of a burden on the people who actually need it.
