Seeing as most roads are 2 lanes each direction i think they should just reappropriate one of the lanes for bikes, ebikes and escooters. They would only need to do that on core routes which are already catered for cars by expressways. They should also introduce a test and license that let's competent riders ride at more practical speeds than the 25kmh. I already ride my bike at speeds of up to 40kmh on the flat under my own power.
