The tech works pretty well but I've found that it will fairly regularly pick up a sign on an off ramp or service road or construction sign that's been there since 2009 and tell you the wrong speed limit. So I guess if it were to automatically limit the car's speed we'd have a bunch of people driving 25 on the freeway. Anyway usually there's also a limiter that you can turn on and have it follow the speed limit.
