Not all of OK is flat, alot of good roads around any of the lakes (& some good river roads too like hwy 10 up the Illinios river)
here. The better road in my opinion here are in eastern side
Of OKlahoma we have lots of lake river and alot of old rolling ( tall) hills
And mountians in south oklahoma with some roads cutting around over and on top of them. Check out some maps of Oklahoma ( & look at the satilite photos maps & topo maps too to see Where the roads are curvy & some great twisties.
Ok now for the other question freeway/hwy on ramps , it is mostly because
Merging traffic Yields to On Coming Traffic is the law , but also in Certain places where
The road engineers did not think of future traffic increasing and higher congestion some
Of the on ramps have have the same short short lane to use for the exit ramp traffic and
That lane is not long enough for all the exiting and getting on hwy traffic. And also i have noticed that no one( or atleast not enough) have any common decency or courtesy to let people in( but is everywhere now days especially big cities every state). But if out of the cities I never see that problem happening.
Here check this out out for Oklahoma.
