At which point charging will take longer because of the lines involved. Hope they're building out. I hear and see no chargers being built. And they totally could be.
They are building out rapidly. I'm not sure why you would "hear and see" them being built. But every day multiple new ones open. https://supercharge.info/
Along my long destination driving routes through rural areas, the charging stations rarely have a car in them. So yes and no to this. Obviously urban and near-urban areas are always packed.
