I'm using the frogpilot branch of openpilot software specifically. This software can only use the maxspeed value. it constantly changes between 90 and 110 on a given stretch of road.

If I set the maximum speed to 90 along the entire highway from one city to another, I would have to set the maximum speed by force in areas of 110 or 120. when reaching the 90 area, I have to manually set the maximum speed again because the maxspeed value does not change. Usually speed cameras are just at the end of fast sections in the 90 area.

If the maxspeed value is 110 or 120, I can set the speed control to a maximum speed of 90 in the winter. With such a solution, you no longer have to manually change the speed limit when driving on the highway.

I think that the maxspeed value should be the absolute maximum speed that is allowed on the given road section. maxspeed:conditional, maxspeed:bus and maxspeed:hgv are marked separately.
