That doesn't seem to make sense...
The faster you go, the more space you need to maintain a safe following distance. If you increase speeds, and drivers increase the gaps between cars, you end up with less capacity.
If you increase speed
without increasing following distances, you end up with a much less safe road and more catastrophic crashes when they happen.
