Suspiciously straight? They’re all very real! I recommend you go ride the course in real life one day. I’m totally biased, but Harrogate is a lovely town and the cycling around there is brilliant.
While expanding the Eastern half of the Yorkshire map would be quite urban, expanding the western half to the north, west or south would be amazing. I doubt it’ll ever happen though.
What they could do as a quick win is to connect the two places where the roads get closest. The first would allow you to go straight ahead at the top of the KOM to connect with the first climb, creating a climb from the lowest to highest point on the course. The second would be a road which goes from the mini-roundabout halfway up the KOM, off to the left towards the sprint point. That would create a “Valley Gardens loop” which would be constantly up or down with NO flat - ideal for everesting.
