Since there is less space available on the inside of the curve, and since road-planners generally want to have the house numbers on both sides of straight stretches be in sync, they will skip some numbers on the inside of the curve. A street with a tight (small-radius) curve will have more skipped numbers than a street with a very gentle, large-radius curve. If the Karlsrue schema doesn't do this, how does it handle curves? Are the lots on the outside of curves always significantly larger than those on the inside of the curves?
