This distinction has been made with engine capacity (number of CCs) for scooters or motorcycles in many places including in the US. I think what you're most experiencing is a result of cars over 2 wheeled vehicles. Cities would be much better if the average American commuted around it with 2 wheeled vehicles, mass transit, or the occasional taxi for trips when traveling with larger items. If you have not traveled around Asia, I recommend it. You start to see a lot of the sickness in American culture. The biggest is a culture that revolves around cars.
