Maybe this is an SI purist and want to see meters per second or nothing? That would be silly because KPH is well used across the metric world, of course

I think it is less. And more than 20% share is more. As in, we do left handed, and we also have a significant portion of our network that is multi track and therefore abides by that convention. As opposed to somewhere that is just left handed, but doesn't have a mature/extensive use of that convention because their network is smaller/sparser
