The track is a little less unforgiving than the other two local tracks you mentioned. As Gingerman is nearly impossible to wreck a car unless there is a mechanical failure. Autobahn is about the same unless you are really driving out of control.
Driving 7/10ths you should be fine but remember the straights at Road America are VERY long and the course is very high speed. Don't try and be amazing your first time there and drive within your limits and you should be fine. Get faster throughout the day, don't start fast and end up slow because you wrecked your car
