Hungary has a great approach. The "cycling" infra is shared with tractors and carts outside of cities. They're basically agricultural access roads.
Not that the side roads were bad. Cars were better behaved than they are in Ireland anyway.
I recently had a ride from Bük to Csepreg which was mainly on a separate cycleway by the road. From Csepreg I was able to enter forest tracks which were very beautiful. I've also noticed quite a bit of new infrastructure in various parts of the country.
I can imagine Hungary becoming a very appealing cycling destination if they continue to develop the network.
