Obvious by your reactions it wasn't on purpose. As well you're concerned enough I don't see this happening again from you.
I used to have a real issue with WSGTC and getting through the first turn cleanly. Draft always threw me off from 2D not showing true speeds. I learned to see where my speed is and where it needs to be. As well you learn that draft and just brake earlier with out thinking after time.
Just remember with out any depth perception we are doing VERY well. It and g forces make real driving easier compared to SIM Racing.
