They are very often correct for me too. But they're by no means perfect. I had a long road trip, and I could watch the speed icons change as I passed a road sign reducing or increasing the limit -- but I also watched the icon indicator not change at all when the signage clearly indicated a change. Do keep an eye on it!I have a 2017 Outback and so far the speed signs icon where I live are correct. I'll keep an eye out now to make sure.
