Chris, there are hidden radar traps to enforce tech speed and minimum speed. There is one unhidden Speed Trap on the plateau, typically about halfway through the course, marked by signs as you approach - the purpose is to provide anyone interested with an official Speed Certificate showing how fast they went through there. Just don't exceed your Tech Speed or go under your minimum speed there. And watch your mirrors in case you're cruising through at your target speed and the person behind is cranking up for a big number on their Speed Certificate. Hope this helps.
