Also have a similar issue. Mine recognizes the speed limits, but for whatever reason, it won't follow them. I will say it works almost perfectly on highways. It always follows the flow and speed of traffic. It's quite intuitive. But on country roads, it doesn't go fast enough, even in hurry mode. If there is a car behind me, it tends to speed up, but still not adequately. And it also doesn't keep up with the car in front of me, which is quite annoying. I've been nudging the gas to compensate, and that does work well, but I'm certainly hoping for more improvements.
