A vehicle miles added tax would, in smart policy districts, allow the curbing of excessive car use, especially for a company like Uber or Lyft. There's also congestion tax, which many cities are already implementing. Some cities just straight up banned non-electric past a certain year, so we're already moving slowly to deal with traffic. I think we'll have the tools we need by the time it's a huge problem. In Boston, the traffic is pretty awful, there are just many cars shoved into a small area with infrastructure based on cow paths from original settlements.
