Right but the challenge works the other ways. It wouldn't take much to support 150 to 180 mph. So Boston to NY which is more or less 200 miles becomes a 90 minute trip on a self driving car. So a good hyperloop gets it to say 30 - 40 minutes. Add to that all the approvals of laying one down in that heavily congested land ownership corridor vs the roads that are already in place. I just don't see it.
- chucksmash 11y ago> It wouldn't take much to support 150 to 180 mph 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.
