This is genuinely something I think makes sense regarding local bus routes given the longevity of light rail and how infrequently routes change, but I also suffer from confirmation bias, so I’m hoping for reasons this would be a terrible idea but obviously would prefer reasons it would be an even more amazing idea than I thought.
That I don’t know, but I assume there’s at least a few models doing that calculation. It’s hard to be accurate as your impact scale goes outward, but I can assure you it’s not going to look good for gas powered cars on the global scale calculations. They’re really hard on the planet and the people around them.
