Do you have a source on this? I did a little napkin math based on these suggested curve radii[1]; namely, I fit a function to the data points in this SageMath worksheet[2] and extrapolated. The fit a) looks good and b) seems to imply that the vastly increased minimum radius of curvature of turns would require significantly re-engineering the interstate highway as it exists today.
