It’s been called the war on cars — the idea that people should cut down on driving to counter climate change.

But within that broad concept lurk many nuanced debates. How will technology and self-driving cars impact the popularity of public transportation? Should we aggressively electrify our municipal bus fleets or lean more heavily on cost-effective biofuels?
