I’m of the side that says just be patient, but I believe that mandated speed governors contribute to this issue. In Ontario where I’d seen this a lot, that is 105km/h, but it seems that they aren’t calibrated well, or engine performance for loaded trucks going up hills means they can’t pass even if they had been partway through it on the downhill. In Nova Scotia, I’ve been passed by large flatbed trucks that have no issue going 125km/h past me going 110.
