That's not true when you're forced to do 10km/h for prolonged periods of time (that's hindrance to traffic and you can usually get a fine for that) because you can't safely overtake a bycicle that's going in a zig-zag way on the lane to avoid a myriad of potholes, or because it's an uphill road and it's too physically taxing for the biker, sice he choose the wrong vehicle for the wrong road.
That's only stress and useless danger for everyone involved.
