here's my five cents i do not think it is practical to give coords for a middle point of routes i have looked around a bit and the only place i happened to find such coords is in bundesautobahn in this example there is an important junction in a city near the centre so it makes sense but in some routes like route which consist of or more separate fragments defining any central point on them is too arbitrary also some routes are important and wide for a part of their length only so their middle is not anything to go by i would be happy with points but i know this is not practical in searching i think an important destination city or big town somewhere between and of their length should be picked but cases like route need more coords maybe inline talk
