Because ultimately that’s a drop in the bucket. Vehicle emissions are only a small part of overall emissions, which includes power generation, agriculture, manufacturing, etc. And even among vehicle emissions, personal transportation makes up only a portion. Lots of emissions come from logistics and supply chain transportation. And to revamping public transportation in the US requires overhauling infrastructure and systems 80 years in the making, which will take time. So while reconsidering public transportation is a good thing in the long term, it will do very little in the short to medium term, which is when we need results.
