And why oh why can't we just have a couple roads like that here in the USA? He have far more and better land to make it happen...
We do. Driven in North Dakota, Montana, or Wyoming lately? I had to drive from Grand Forks ND to Minot ND several times back in the late 90s and the road was so dead straight, flat, and void of other drivers I could have taken a 20-minute nap and not veered out of my lane.
