How can I set my max speed in Maps for better accuracy?

The speed limit in The Netherlands between 06:00 and 19:00 is 100 km/hr.

For a truck is always

80, for a car and caravan 90.

I would like it that you can set your max speed you have to or like to drive in maps.

Then the estimate time of arrival is more accurate
