1) If you want to look at a professional map of Czechia, I'd recommend www.mapy.cz over google maps as that is the most used and far more detailed map. 2) I agree that the discontinuities are ugly, but they reflect the state on the ground. That section around Sulec is a trunk instead of a primary due to the fact that it is a section of future motorway built to motorway standard. While your system heavily preferences "importance" of roads, our local system reflects reality. Declaring the entire road from Pilsen to České Budějovice as trunk due to its importance loses the information that there is a section that was built as a motorway link to Písek. I can already tell that the road is important because it links Pilsen and České Budějovice (by looking at the map), but I also want to know that it was built as a primary road and not as a trunk - that means that I'm going to expect more single-level junctions and only two lanes for most of the way.
I agree, our trunk roads are a little fuzzy on their definition, but elevating random primary roads to trunk is a loss of data for us. Touching anything else than reclassifying primary to trunk et vice versa will certainly be considered as vandalism in Czechia. You are demonstrating that you can guess the road class from other data. I think it's cute, but does not match on-the-ground data in countries where road classification is well-defined. Look, I've spent a lot of time on this and I have better things to do. Fill in the info for your regions on the wiki and then we can see what we can do. Until then, bear in mind that "harmonising" European roads will likely get you banned. I don't want to sound like I'm threatening you, but I've probably spent all the time I'm willing to spend on arguing with some random person who wants to break our local road classification system "because it will look nicer".
