@organicmaps - thx.
I think it's not a question of a faulty algorithm. When driving in the city I like to have a bigger zoom, but sometimes I ‘pinch’ the screen to see a bigger map or on the contrary a smaller piece of it. I would like to be able to set a default zoom so that the map returns to it when I start. For speeds up to 50 km/h because that is usually the limit in central European cities.
