We're talking about long distance roads. The purpose of these should be to accommodate travel, not prohibit it.
Here in Germany, the Autobahnen do a surprisingly well job, although I agree that a speed limit of around 200 km/h makes sense because those with cars capable of going above that are so much faster than others on the road that even someone with perfect reflexes and racing-grade brake systems will have a hard time avoiding an accident.
