You are spot on about segregation. Yes, walking and biking are for undesirables. The suburbs are built for cars and cars only. Poor people (African, etc) can't afford the large lots, the minimum size of residence, the HOA and lawn maintenance, car required to go anywhere. This is how you can do segregation without violating any laws. Usually, most people don't admit that these are the real goals. I'm surprised that you are openly admitting that segregation is what we want. I guess times are changing!
