This is Paris in the EU. Home to the densest (most stations per square mile) metro system in the world.
Trust me, you don’t need a bus, nor will you walk for 3 hours.
Don’t assume that every city in the world lacks resent public transport. That seems to be a uniquely American thing.
Also, I've taken public transport in major EU cities. It's a miserable experience compared to less dense city with a car.
It basically discourages me from living in a large city, it's such a terrible experience. Which is, of course, my choice.
But I think lots of people are going to start making that choice.....
If we take the bottom table, "US Diet, typical", it looks like it is 1000 for driving, 230 for walking. That is more than 4x lower GHG emission by walking, per mile.
Which numbers from that article are you comparing?
It is not. On a CO2 per mile bases cars emit less than non-vegan humans, because it takes a lot of energy to grow food. If you put 2 people in the car it's not even close.

> but after it takes place everyone agrees things are much much better with less cars and no one wants to go back.
Speak for yourself. Every place that has done that is basically a place I will never go to. Since I'm not there anymore I can't complain, right?
It's especially stupid when a downtown of a large city does that - God help anyone who needs city services and lives in the suburbs. (Are you expected to walk for 3 hours? Spend a ton of money on a taxi? There is no bus.) What ends up happening is the city and the surrounding area mentally split into two, and they fight politically.
