An improvement.  

I don't think there was ever any questioning as to whether or not the car failed the test. The question is...... Was the car tested at a speed and angle in which NASCAR fully expeceted those results. And thus was able to reverse engineer those data points. You can't fix something until you now what breaks!

As far s rear view cameras.....their just getting started. You might want to check my post over on SJDR and then do some critical thinking. Then listen to the daily narratives and see where it leads you. It's not a matter of if, only when.
