You could do this based on estimated m/s, a motorway at over 100km/hr is a minimum of 28m/s, obviously if maxspeed is available that could nail it down much better.

Lots of unsurfaced roads are maxspeed=100 but you wouldn't be able to sustain that all the time, I'd say a 30% hit at a guesstimate.

calming devices drop you to 15km/hr or there abouts.

I was hoping they would :)
