We let the teenager drive twice on this trip.The first time was in the parking lot/campground of a KOA. That went well. The brakes are kind of tricky so I was a little worried. You really have to press them. All the way.
The second time was on the highway when we left the Cheyenne, Wyoming rest area. OMG. That was freakin scary. I love her. I think she's a pretty good driver. But no teenager should drive on an 80 MPH freeway with trucks entering and passing 18-wheelers and whatnot. And that was it. That's all the driving she did. I was not emotionally stable enough for any more than that.
