First off, the Netherlands brought back their trams, and it's awesome. Trams are the most accessible form of transportation for people with mobility or financial issues, and they contribute very positively to the local economy by increasing foot traffic around local businesses. And as I said, they're cheaper to run and maintain than buses.
Second, a 70% traffic reduction in cities would be around a 50% reduction in car usage overall, which was the thing you started this argument by complaining about. My radicalism caused you to push for a compromise that you previously considered too extreme. Get got. Being radical works.
