Water usage is probably my biggest. Living in a high desert, my wife and MIL see no problem with filling one side of the sink with hot soapy water to wash a few dishes because “that’s just how I’ve always done it”, to watering the grass and plants for hours. All of this makes me mental.
Sidewalks should be wide enough for both a bike and a pedestrian lane to fit in safely, ideally with some paving protection for the pedestrians. Bikes in the car traffic are dangerous.
Bringing new regulations to old infrastructure always makes a sacrifices.
